Effective date: 29 August 2026
Last updated: 6 September 2026

This Privacy Policy explains how AppAuxin (“AppAuxin”, “we”, “us”, “our”) handles information in connection with:

• the website and blog at appauxin.com, and
• every mobile application we publish on Google Play under the developer name AppAuxin.

If you have any question about this policy or about your data, write to us at hello@AppAuxin.com. We answer within 30 days.

---

1. Summary

• None of our apps require an account. We never ask you for your email address, phone number or payment card details. (Age Calculator lets you optionally type a name or label such as “Mum” beside a birthday you save; that text stays on your device — see section 6.3.)
• We do not operate servers that receive your personal data. Whatever our apps calculate, measure or save stays in the app’s private storage on your device unless a section below says otherwise.
• Most of our apps show advertisements. Advertising is the one part of our apps that does send data off your device — advertising identifiers, device information and an approximate location derived from your IP address — to Google and our advertising partners. Section 5 sets this out in full.
• Internet Speed Meter collects location data to display the name of the WiFi network you are connected to, including when the app is closed or not in use. That location is used on your device only and is never uploaded, sold or shared. Its optional Speed Test is the one exception: it is powered by SpeedChecker Ltd., which does receive a location. See section 6.1.
• We do not sell personal information and we do not use your data to build profiles for our own purposes.

2. Which apps this policy covers

This policy applies to every app published by AppAuxin on Google Play, currently:

This table is the authoritative statement of which apps show advertising and which offer purchases. Sections 5 and 6 describe what advertising and purchases involve in general; whether they apply to a particular app is determined by its row above. If we publish a new app, or add advertising or purchases to an existing one, we update this table and that app’s section in section 6 before the change reaches you, and we revise the “Last updated” date at the top of this policy.

---

3. The website and blog (appauxin.com)

Server logs. Our hosting provider records standard web-server information when you visit: your IP address, browser and operating system, the page you requested, and the page you came from. This is used to keep the site running and secure and to understand aggregate traffic. We do not use it to identify you personally.

Cookies. The site uses cookies that are necessary for it to function and to remember display preferences.

Advertising on the blog. We display Google AdSense advertising on our blog articles. Google and its partners use cookies and similar technologies to serve and measure those ads, and — depending on your settings and where you live — to personalise them. Google’s use of information from sites that use its services is described at policies.google.com/technologies/partner-sites, and you can control ad personalisation at adssettings.google.com and policies.google.com/technologies/ads.

Consent for visitors in the EEA, the UK and Switzerland. Before personalised advertising cookies are set on the blog, a consent banner asks whether you agree. If you decline, you will still see ads, but non-personalised ones. You can change your answer at any time by reopening the banner from the link in the site footer, or by clearing this site’s cookies in your browser.

Contacting us. If you email us, we receive whatever you choose to send and use it only to reply to you.

What the site does not have. There are no user accounts, no registration, no comment sections and no newsletter signup, so there is nothing for us to store about you beyond the above. You can block or delete cookies in your browser at any time; the site will still work, but ads may become less relevant and some preferences will not be remembered.

4. What our apps do not collect

Across every app listed in section 2, we do not ask for or collect:

• your name, email address, phone number or postal address;
• any account, login or password;
• your contacts, calendar, call log, SMS messages, microphone or camera;
• your payment card details (see section 5.4);
• your photos or files. Two apps touch files by design and neither sends them anywhere: Status Saver saves the specific media you choose to save (section 6.2), and All Document Reader opens and displays the documents you choose to view (section 6.6).

We have no analytics SDK, no crash-reporting SDK and no user-tracking SDK of our own in any app. We do not receive a copy of your data from our advertising partners; they report aggregate performance figures to us, not information about you.

---

5. Advertising in our apps

The apps marked “Yes” in section 2 are free and are funded by advertising. This is the main way data leaves your device, so we describe it in detail.

5.1 Who serves the ads

The advertising SDK in our apps is Google AdMob. AdMob uses mediation: for each ad request it may invite other advertising networks to bid, or fall back to them in turn, and shows whichever ad wins. The mediation partners we have enabled are:

• Liftoff Monetize (formerly Vungle) — Liftoff Mobile, Inc.
• Unity Ads — Unity Technologies
• Mintegral — Mintegral International Ltd.

Each of these is an independent company and an independent data controller for what it collects. Their privacy policies are:

5.2 What the advertising SDKs collect

When an ad is requested or displayed, Google and the mediation partner handling that request may collect:

• your device’s advertising identifier (the resettable Android Advertising ID, or a Google-provided app-set ID);
• your IP address, and an approximate location derived from it — typically at city or region level;
• device and app information: device model, manufacturer, operating system version, screen size, language, time zone, mobile carrier, network type, and which of our apps you are using;
• ad interaction data: which ads were requested and shown, whether you viewed, clicked or closed them, how long they were on screen, and whether an ad led to an app install.

They use this to select an ad, cap how often you see the same one, measure whether it worked, detect click fraud and invalid traffic, and — where permitted — personalise the ads you see. Precise GPS location is not collected for advertising in any of our apps. Internet Speed Meter, the only app that holds location permission, contains no advertising SDK at all.

5.3 Your choices about advertising

• If you are in the EEA, the UK or Switzerland, the first time you open an ad-supported app you will see a consent form provided by Google’s User Messaging Platform, asking whether you agree to personalised advertising. Your answer is passed to Google and to every mediation partner. If you refuse, you will still see ads, but they will be non-personalised — selected from context rather than from data about you.
• Anywhere in the world, you can limit ad tracking on your device: Android Settings → Privacy → Ads, where you can reset your advertising ID or delete it entirely. Deleting it stops apps from receiving an advertising identifier at all.
• You can reopen that consent form and change your answer at any time from the app’s Privacy options entry in its settings.
• You can opt out of Google’s personalised advertising at adssettings.google.com, and out of each mediation partner using the links in the table above.
• Uninstalling an app stops all further advertising data collection by that app.

5.4 Purchases

Some apps offer optional in-app purchases, handled entirely by Google Play Billing. Your payment is processed by Google under Google’s privacy policy. We never see or receive your card number, bank details or billing address. We receive only the confirmation needed to unlock what you bought.

5.5 If you buy the ad-free upgrade

Where an app offers a purchase that removes advertising, buying it does more than hide the ads: the advertising SDKs described in section 5.1 are not started at all for that app once the purchase is active. No advertising identifier, device information, IP-derived location or ad interaction data is collected or sent to Google or to any mediation partner from then on, and the whole of section 5 stops applying to you for that app.

Your purchase is tied to your Google account by Google Play, so it follows you to a new device or a reinstall. To check or restore it, the app queries Google Play Billing for your entitlement; that query goes to Google, not to us.

6. App-by-app details

6.1 Internet Speed Meter: Data Use

com.AppAuxin.internet_speed_meter — contains no advertising SDK.

Internet Speed Meter shows your live internet speed in a notification, a home screen widget and inside the app, and keeps a history of how much mobile and WiFi data you have used.

Permissions and what they are for

6.1.1 Location data — full disclosure

Internet Speed Meter collects location data to enable the display of the connected WiFi network name (SSID) in the speed notification, on the home screen widget and inside the app, even when the app is closed or not in use.

Why location is needed. From Android 8.1 (Oreo) onward, Google places the connected WiFi network name behind location permission: an app may only read the SSID if it holds that permission and device location is switched on. Internet Speed Meter does not want your position — it needs the permission because Android put the network name behind it.

Why background location is needed. The speed notification and the widget keep running while you use other apps or while the screen is off. For the WiFi name to stay correct there, the app must read the network name while it is not in the foreground. Android classifies that as background location, which is why the app asks for “Allow all the time”.

How location is used.

• Solely as the key that lets Android return the connected WiFi network name — and, separately and only when you start one, to let the Speed Test pick a nearby test server.
• Outside of the Speed Test, the app never asks Android for your position at all. It contains no call to any positioning API: it does not request location updates, does not read your last known location, and does not use a geocoder. It queries the location system for exactly one thing — whether location services are switched on, which Android requires before it will return a network name.
• Your coordinates are therefore never recorded, never written to a location history, never attached to your usage statistics, and never used to infer where you live, work or travel.

How location is shared. For the WiFi network name feature it is shared with nobody: not with AppAuxin, not with advertisers, not with data brokers, not with any analytics provider. This app contains no advertising SDK. The only case in which location-derived data leaves your device is a Speed Test you start yourself (6.1.2).

What is retained. No location is stored, because none is ever obtained. The WiFi network name is different and we want to be precise: while “Show WiFi SSID” is switched on, the network name is written, with a timestamp, into the speed history and connection history the app keeps in its private storage — that is what draws the speed chart and the connection timeline. Those records are capped (at most 1,440 speed samples and 200 connection changes per day) and are kept until you reset statistics in the app, clear the app’s data, or uninstall it. That history is a record of which networks you connected to and when, so treat it as you would any list of your WiFi networks. It never leaves your device, and it is not included in the usage summary or CSV export features, which contain only dates and byte totals.

Consent and control. Before the app requests location permission it shows an in-app disclosure describing exactly what is above, and requests the permission only if you tap to continue. The feature is optional: decline and everything else — live speed, usage history, widget, notification — works unchanged; the notification simply omits the WiFi name. Withdraw the permission at any time in Android Settings → Apps → Internet Speed Meter → Permissions → Location, or switch the feature off in Preferences → Advanced settings → Show WiFi SSID.

6.1.2 Speed Test and SpeedChecker Ltd.

The Speed Test screen is powered by the SpeedChecker SDK from SpeedChecker Ltd. It is optional — you have to open it and start a test.

Location permission is mandatory on the free tier. SpeedChecker’s own documentation states that the free version of the SDK “requires location permission to be able to perform a speed test” and that it “collects data on network performance from your app and shares it with Speedchecker and our clients”. Those restrictions do not apply to their paid tiers, which we do not use. This is why the Speed Test asks for location even though the rest of the app’s location use is confined to reading the WiFi network name.

How SpeedChecker determines your location. According to SpeedChecker’s own privacy and consent documentation, the SDK works out an approximate position using any of:

• your device’s GPS coordinates;
• the MAC addresses of nearby wireless routers;
• the signal strength of nearby mobile network towers.

SpeedChecker states that it gathers this “anonymously in a form that does not personally identify the user”.

What is sent, and to whom. When you run a test, SpeedChecker Ltd. receives your download and upload speed, latency and jitter; your IP address, internet service provider, connection type, device information and the test server used; and the location described above. SpeedChecker states that, on the free tier, this data “may be shared with third parties to compile aggregate information about network statistics and bandwidth usage in particular areas”.

Your control. On the free tier this sharing is a condition of the test running and cannot be switched off inside the app. The app therefore shows you a disclosure describing all of the above and asks you to confirm before your first test. If you would rather not share this, simply do not run a speed test — no other part of Internet Speed Meter uses the SpeedChecker SDK, and every other feature works without it. You can also revoke location permission afterwards in Android Settings → Apps → Internet Speed Meter → Permissions → Location.

SpeedChecker’s own privacy policy: speedchecker.com/privacy-policy.html. Their plugin’s privacy and consent notes: github.com/speedchecker/flutter_plugin/wiki.

6.1.3 Usage statistics

The app records data transferred over mobile and WiFi per day and, if you grant Usage Access, per installed app. This is stored only in the app’s private storage and is never uploaded. It is removed by the app’s “Reset statistics” function, by clearing app data, or by uninstalling. The Share and Export CSV features create a file containing dates and byte totals which goes wherever you choose to send it — that is your action, not an automatic transmission. Usage Access can be revoked at Android Settings → Apps → Special app access → Usage access.

6.2 Status Saver – Video Download

com.AppAuxin.StatusSaver — contains advertising (section 5) and an optional in-app purchase that removes it (sections 5.4 and 5.5).

The app lets you view and save the status photos and videos that other people have shared with you in WhatsApp and WhatsApp Business.

File access. To find those status files the app needs to read the folder your messaging app stores them in. How it asks depends on your Android version. On Android 9 and earlier it uses the classic read/write storage permission (READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE, both declared with maxSdkVersion="28" so they are never requested on newer releases), because those versions offer no narrower way to reach that folder. On Android 10 and later it uses the Android Storage Access Framework, where you pick the status folder yourself in the system file picker and the app can read only what you selected. The app does not declare or request “All files access” (MANAGE_EXTERNAL_STORAGE) on any Android version.

What we do with it. The app reads status media so it can display it and, when you tap save, copies it into your device storage. We do not upload, transmit, index or inspect your files. Nothing you view or save reaches AppAuxin or any third party. Saved items stay on your device until you delete them; uninstalling the app does not delete files you saved. You can withdraw file access at any time in Android Settings → Apps → Status Saver → Permissions.

What this app’s Data safety entry means. Google Play shows “Device or other IDs” as collected and shared for Status Saver. That is the advertising identifier and device information described in section 5.2, sent to Google and our mediation partners. It does not refer to your files: the status media you view or save is never collected, transmitted or shared. If you buy the ad-free upgrade, Google Play also records that purchase (“Financial info” / purchase history) as described in sections 5.4 and 5.5; we receive only the confirmation needed to unlock it.

Not affiliated. AppAuxin is not affiliated with, endorsed by, or connected to WhatsApp LLC or Meta Platforms, Inc. Please respect other people’s content and copyright, and get permission before re-sharing anything that is not yours.

6.3 Age Calculator: Date of Birth

com.AppAuxin.AgeCalculator — contains advertising (section 5) and optional in-app purchases (section 5.4).

You enter dates of birth, and optionally names or labels, to calculate ages and set birthday reminders. That information is stored only on your device, in the app’s private storage. We never receive it. Birthday reminders are generated locally by your device and require notification permission; no reminder data is sent anywhere. Delete an entry in the app, clear the app’s data, or uninstall it to remove this information.

What this app’s Data safety entry means. Google Play shows several categories as collected and shared for Age Calculator. To be clear about which is which:

• Location — approximate only, derived from your IP address by the advertising SDKs in section 5. This app has no location permission and never reads your device’s position.
• Personal info — the birth dates and any names or labels you type in. These are held in the app’s private storage on your device and are not transmitted to us or to anyone else.
• Device or other IDs and App activity — the advertising identifier, device information and ad interaction data described in section 5.2, sent to Google and our mediation partners.
• Financial info / purchase history — if you make an in-app purchase, the transaction is handled by Google Play Billing (section 5.4). We receive only the confirmation needed to unlock what you bought, never your payment details.

Everything except the birth dates and labels you enter leaves the device solely through advertising or Google Play Billing.

6.4 BMI Calculator

com.AppAuxin.bmi_calculator — no advertising, no data collected.

Height, weight, age and sex are entered by you, used to compute a result, and stored only on your device. Nothing is transmitted. This app declares “No data collected” in its Data safety entry, and that is accurate.

BMI Calculator is for adults 18 and over. The measurements you enter — height, weight, age, sex and optional waist, neck and hip — are health data, and they never leave your device. The app can show local reminders if you turn them on; these are scheduled on your phone. Android’s own backup may copy app data to your Google account, which you can turn off in your phone’s settings.

6.5 Style Calculator and Simple Calculator – MathLite

com.AppAuxin.ios_calculator, com.AppAuxin.MathLight — contain advertising (section 5) and an optional in-app purchase that removes it (sections 5.4 and 5.5).

These are calculators. Your calculation history and appearance preferences are stored on your device only.

What their Data safety entries mean. Google Play shows “Device or other IDs” as collected and shared for both apps. That is the advertising identifier and device information described in section 5.2, sent to Google and our mediation partners. Both apps also offer an optional ad-free purchase, so Google Play records that transaction (“Financial info” / purchase history) as described in sections 5.4 and 5.5; we receive only the confirmation needed to unlock it. Apart from advertising and that purchase confirmation, these apps send nothing anywhere.

6.6 All Document Reader

com.appauxin.alldocumentreader — no advertising, no in-app purchases, no data collected.

All Document Reader is a read-only viewer for documents that are already on your device: PDF, Word, Excel and PowerPoint files, OpenDocument files, EPUB, RTF, plain text, CSV, Markdown, code, images and ZIP archives. Every file is opened and rendered on your phone or tablet. The app never edits or rewrites the documents you open.

The app cannot send anything anywhere. The released build does not request Android’s INTERNET permission at all, so it has no ability to make a network connection. It contains no advertising SDK, no analytics SDK, no crash reporter and no Firebase, and it does not request an advertising ID. No document, file name, folder name, search term or reading position leaves your device.

All files access. The app can ask for Android’s “All files access” (MANAGE_EXTERNAL_STORAGE) so that it can list the documents already stored on your device in its own library. The request is optional and is only made from a screen that explains it first; if you decline, everything else still works — you can open documents through the system file picker, or from another app. On Android 12 and older the app instead uses the ordinary storage read permission. Access is used to find and read documents; the app does not modify or delete your files.

What is kept, and where. Your recently opened list, favourites, bookmarks, reading positions and appearance settings are stored in the app’s private storage on the device. When another app hands a document to All Document Reader — an email attachment, for example — a temporary copy is placed in the app’s private cache so it can be displayed. All of it is removed when you uninstall the app, and Settings has separate controls to clear the recents list, the saved reading positions and the cached copies. Unlike some of our other apps, this one switches Android’s own backup off and excludes its data from cloud backup and device transfer, so its list of your documents is not copied to your Google account.

When you leave the app. Opening a link found inside a document, using “open with another app”, sharing a document, or sending us feedback hands the file or address to an app you choose; what that app does is covered by its own privacy policy, not ours. The rating prompt uses Google Play’s own in-app review feature, which tells us nothing about you.

What its Data safety entry means. This app declares “No data collected” and “No data shared” on Google Play, and that is accurate.

7. Legal bases for processing (EEA / UK)

Where the UK GDPR or EU GDPR applies to you, we rely on:

• Consent — for personalised advertising, and for optional permissions such as location in Internet Speed Meter. You may withdraw consent at any time, as described in sections 5.3 and 6.1.1.
• Legitimate interests — for non-personalised advertising, fraud and invalid-traffic prevention, and keeping our website secure and functioning.
• Contract — for delivering an in-app purchase you have made.

---

8. International transfers

We do not operate servers of our own, so we do not ourselves transfer your data anywhere. Our advertising partners, Google, and SpeedChecker operate globally and may process the data described in sections 5 and 6.1.2 in countries other than yours, including the United States, under Standard Contractual Clauses or equivalent safeguards described in the policies linked in this document.

---

9. Retention and deletion

• On your device — settings, statistics, saved media, calculation history and entered dates remain until you delete them in the app, clear the app’s data, or uninstall it. We cannot delete them for you because we cannot reach them.
• Advertising data — held by Google and the mediation partners as independent controllers, under their own retention schedules. We cannot delete it for you, which is why the Google Play Data safety entries for our ad-supported apps state that the data they collect cannot be deleted by us. Use the opt-out routes in sections 5.1 and 5.3, or contact those companies directly to ask them to delete it.
• Website logs — retained by our host for a short period for security and diagnostics.
• Emails you send us — kept only as long as needed to deal with your query.

---

10. Security

Data our apps hold stays in Android’s private per-application storage, which other apps cannot read. Our website is served over HTTPS. Email you send us is held in our mailbox and used only to answer you. No method of storage or transmission is perfectly secure, but we take measures appropriate to the very limited amount of data involved.

---

11. Children

Our apps are general-purpose utilities and are not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through one of our apps or our site, contact hello@AppAuxin.com and we will delete it.

---

12. Your rights

Depending on where you live you may have the right to access, correct, delete, port or restrict the processing of your personal data, to object to processing, to withdraw consent, and to complain to your data protection authority. California residents additionally have the rights described on our https://appauxin.com/california-consumer-privacy-act-ccpa/”>CCPA page, including the right to know and the right to delete. We do not sell personal information, and we do not share it for cross-context behavioural advertising other than through the advertising partners disclosed in section 5, whose opt-outs are linked there.

Because our apps keep your data on your own device and we hold no copy, you can exercise most of these rights directly and immediately: revoke a permission in Android Settings, reset or delete your advertising ID, use an app’s reset function, clear its data, or uninstall it. For anything else, or for a request about the website, write to hello@AppAuxin.com and we will respond within 30 days. For data held by Google, Liftoff, Unity, Mintegral or SpeedChecker as a result of using our apps, please also contact those companies using the links in this policy — they control that data, not us.

---

13. Changes to this policy

We may update this policy from time to time. When we do we will revise the “Last updated” date above, and where a change is significant we will describe it in the affected app’s release notes on Google Play.

Where a change materially affects something we rely on your consent for (section 7) — personalised advertising, or location in Internet Speed Meter — we will ask you again rather than treat continued use as agreement: the consent form or the location disclosure will be shown to you afresh. For all other changes, continuing to use our website or apps after the “Last updated” date means you accept the revised policy.
