Effective date: 19 August 2026
Last updated: 19 August 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, other than the specific media you choose to
  save in Status Saver (section 6.2).

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).

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 older versions it
requests broad storage access (“All files access” /
MANAGE_EXTERNAL_STORAGE), because those versions offer no
narrower way to reach that folder; on newer versions 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.

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.

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.

6.5 Style
Calculator and Simple Calculator – MathLite

com.AppAuxin.ios_calculator,
com.AppAuxin.MathLight — contain advertising (section
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. It is the only
data these apps send anywhere.

---

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 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.
