Witsprint privacy policy

Last updated November 7, 2026. This policy covers the Android app Witsprint: Daily Brain Games (com.tinyfair.witsprint) published by Tinyfair on Google Play.

The short version

The app works on your phone. We do not have accounts or servers, and we never receive your scores, your streak or personal details. Data leaves your phone only for ads, purchases, crash reports and anonymous usage statistics (Google), and for a small settings file the app downloads from our website, as described below.

Data that stays on your phone

Scores and streak: Your game results, levels, streak, shields and settings are saved in the app on your phone.
Reminder: The daily reminder is scheduled on your phone; you choose the time and can turn it off.
Purchases: Handled by Google Play; we never see your payment details.

Settings file from tinyfair.my.id

When it starts, the app downloads a small settings file from https://tinyfair.my.id/config/witsprint.json (the minimum app version and which ad formats may appear). The request sends no personal data and no identifier. Like any web request, our web host sees your IP address in its standard server logs; we do not use it to identify you or link it to anything else. Android Auto Backup may include the app's scores and settings in your Google account backup if you have it turned on.

Ads (Google AdMob)

The free version shows ads from Google AdMob: banner ads on the Today, Games and Stats screens, at most one full-screen ad a day after you finish the daily workout (never in your first session), and a video ad only when you choose to watch one, for example to get a streak shield, one more practice game or 24 hours of Pro. There are no ads before or during a game, on the results screens, or when the app opens. Ad content is limited to no higher than the PG rating, and dating, social casino and similar ads are blocked. To show and measure ads, Google may collect your device's advertising ID, an approximate location from your IP address, information about ad interactions, and diagnostics. Your scores are never passed to the ad SDK. In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent first, and you can change it later under Settings, Privacy options. You can reset or delete your advertising ID in your Android settings. See how Google uses information from apps that use its services. Pro removes all ads.

Crash reports (Firebase Crashlytics)

If the app crashes or hits a serious error, it sends a crash report to Firebase Crashlytics, a Google service that helps us find and fix the bug. A report contains the error and where it happened in the code, the app version, the device model, the Android version, and a random installation ID that is not linked to you, your Google account or your advertising ID. It never contains your scores, your streak or anything that identifies you. Reports are kept for 90 days. See Firebase privacy and security.

Usage statistics (Google Analytics for Firebase)

To learn which features people use and where the app can be better, the app sends a few usage events to Google Analytics for Firebase, such as that the daily workout was started or finished, a game was finished (with the game name and level), a shield was used, or the Pro offer was shown or Pro was bought. Events never contain anything you type. Firebase adds the app version, device model, Android version, country, a random app instance ID and, when ad consent allows it, your advertising ID. Collection follows your choice (Google Consent Mode). We do not use Google signals, we do not send a user ID, and we do not sell this data. In the European Economic Area, the United Kingdom and Switzerland, statistics are only collected if you allow it in the consent form (Settings, Privacy options lets you change this). Data is kept for 14 months. See Firebase privacy and security.

Purchases (Google Play)

Pro is sold through Google Play Billing, as a yearly subscription with a 7 day free trial, a monthly subscription (you can cancel either anytime in Google Play) or a one-time purchase. The app reminds you one day before a free trial ends. We do not see your payment details; Google Play tells the app only whether Pro is active.

Permissions

Notifications, asked only after your first workout, for one daily reminder at the time you choose and one reminder the day before a free trial ends; the reminder is set again after the phone restarts. Vibration for game feedback. No location, camera, microphone, contacts, storage or exact alarm permission: backup files use the Android file picker. Google's ad and purchase libraries add the advertising ID, network state and billing permissions. Internet is used for ads, purchases, crash reports, usage statistics and the settings file described above; the games themselves never need it.

Children

The app is not directed at children under 13 and we do not knowingly collect information from them.

Your choices and deleting data

Witsprint has no account and keeps no data on our side, so you can delete almost everything yourself, right away.

How to delete your data

In Witsprint open Settings, Data, Delete all data, and confirm. This deletes your streak, shields, scores, levels, game history and settings from this phone at once.
Or uninstall Witsprint, or clear its storage in Android settings (Apps, Witsprint, Storage, Clear storage).
Backup files you saved yourself with Pro stay where you saved them until you delete them. If Android backup is on, Google may keep a copy of the app data in your Google account backup until Android replaces or removes it; you can manage it in Android settings.
Ads and statistics: in Witsprint open Settings, Privacy options to change or withdraw consent, and reset or delete your advertising ID in Android settings.
To ask us to delete crash reports and usage statistics from your installation, email support@tinyfair.my.id with the subject "Delete my Witsprint data". We delete what we can find in Firebase within 30 days and reply when it is done. Because there is no account, we may ask for details shown in the app to find the right data.

What is deleted and what is kept

On your phone: everything Witsprint stores is deleted at once by the steps above.
Crash reports (Firebase Crashlytics): deleted on request, otherwise kept for 90 days.
Usage statistics (Google Analytics for Firebase): deleted on request, otherwise kept for 14 months.
Ad data: held by Google under its own retention rules; we have no copy. Use the ad settings above.
Purchases: Google Play keeps the record of your purchase or subscription for payments and refunds; we do not hold it. Deleting app data does not cancel a subscription: cancel it in Google Play, Payments and subscriptions.
Web server logs from the settings file request: kept by our web host for a limited period, then deleted.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions: support@tinyfair.my.id.
