Privacy Policy
Effective date: October 5, 2026
TRT Tracker & Calendar ("the app") is a personal log for testosterone therapy, published by Chinese Powered ("we", "us"). This policy explains what data the app handles, where it goes and what you control.
The short version: what you log stays on your phone. There is no account and no cloud, we run no servers, and we never receive your health information. The free version shows ads from Google, whose SDK collects device and ad data as described below, but it never gets anything you log.
Your health log stays on your device
Everything you enter — your medications and schedule, injections, injection sites and how they healed, lab results, daily check-ins, side effects, weight, blood pressure, supplies on hand and notes — and your settings are saved in the app's private storage on your phone. The app has no accounts, no sign-in and no sync, and it never uploads your log to us or to anyone else: we cannot see it. Deleting the app, or "Delete all data" in its Settings screen, erases it. Your phone's own device backups (iCloud or Google) may include it, under your Apple or Google backup settings.
We do not sell your health information, use it for advertising, or pass it to the ad SDK. Ad requests carry no keywords and nothing about what you log.
Backups, reports and exports you make
"Back up to a file", the doctor report (a PDF) and the spreadsheet export (CSV) are made on your phone, then your phone's share sheet opens. You choose where each goes — Files, an email, a printer, a cloud drive — and from then on that copy is handled by the service you picked. The files are not encrypted, so keep them somewhere private. "Restore from a backup" reads a file you choose on your phone; nothing is downloaded from us.
App lock
The optional app lock uses your phone's own Face ID, Touch ID, fingerprint or passcode check. The app only learns whether the check succeeded; your biometric data never reaches the app or us.
Reminders
If you allow notifications, the app schedules local reminders on your phone: your doses (with "Log it" and "Skip this dose" buttons, which open the app to record your choice), an optional follow-up if a dose isn't logged, a reminder when bloodwork is due, an optional daily check-in and a reminder before your supplies run low. No push server is involved. Reminders name your medication and dose unless you turn on "Discreet notifications" in Settings, which keeps them out of what appears on your lock screen. You can turn reminders off in the app or in your phone's settings.
Home screen widget
If you add the app's widget to your home screen (or, on iPhone, your Lock Screen), it shows your next dose: when it's due, the medication and dose, and the next site. The app hands that to the widget on your phone; nothing is sent anywhere. With "Discreet notifications" on, the widget leaves out the medication's name and dose. Anyone who can see your screen can see the widget, so remove it if that matters to you.
Advertising (Google AdMob)
The free version shows ads served by Google AdMob: a banner, an occasional full-screen ad after you save an entry, and videos you can choose to watch to unlock a Pro feature for an hour. TRT Tracker Pro removes all ads, and the ad SDK isn't started at all for Pro users.
When an ad is requested, Google's SDK may collect device information such as advertising identifiers, IP address, approximate location derived from it, and ad-interaction and diagnostic data, used for ad delivery, measurement and fraud prevention. Google receives nothing you log in the app.
- Consent: where the law requires it (for example in the EEA, the UK and Switzerland), Google's consent form is shown before any ad is served. Where that form applies, "Ad privacy options" in the app's Settings screen reopens it.
- On iPhone, the app asks for App Tracking Transparency permission. Ads use your device's advertising identifier only if you allow it, and are otherwise non-personalized. You can change this any time in Settings › Privacy & Security › Tracking.
- On Android, you can reset or delete your advertising ID in your phone's Google settings.

Purchases (App Store and Google Play)
TRT Tracker Pro is bought through Apple's App Store or Google Play, which process the payment; we never see your payment details, name or email. The app checks your purchases with the store directly from your phone — there is no purchase server of ours and no third-party purchase service — and "Restore purchases" simply asks the store again. Apple's or Google's privacy policy covers the purchase itself.
Analytics
The app contains no analytics or crash-reporting SDK, and we don't track how you use it. If you have chosen to share diagnostics with app developers in your phone's settings, Apple or Google may give us anonymous crash reports and aggregate usage statistics; you control that in your phone's settings.
Security
Your log lives in the app's private storage, protected by your phone's own passcode and encryption; the app lock adds a second gate. Backup and export files you create are ordinary files, so treat them like any other private document.
Children
The app is meant for adults managing their own treatment. It is not directed at children, and we do not knowingly collect personal information from children.
Your choices
- Your log: back it up, export it or erase it from Settings ("Delete all data"), or delete the app. Because we never receive it, there is nothing of yours on our side to access, correct or delete.
- Ads: the consent form where it applies, App Tracking Transparency on iPhone, your device's advertising-ID settings, or remove ads with Pro. For data Google collects for ads, Google's own controls apply.
- Reminders and the widget: turn reminders off, or make them and the widget discreet, in Settings; remove the widget from your home screen any time.
- Subscription: manage or cancel in your App Store or Google Play account settings (Settings › Manage subscription in the app takes you there).
Changes
If a future version changes any of the above, this policy will be updated before that version ships, with the date above revised.
