Privacy policy

Effective 11 October 2026. Applies to the iPhone app Estim8: Guess the value ("Estim8"), made by Wakalo.

What stays on your iPhone

To work, the app keeps the following on your device only:

• Your history: for each finished day, the set number, your three guesses, the true values and your scores. This is what streaks, your week and Calibration are made from.
• Today's progress, so you can leave and continue a set the same day.
• Your settings: whether the daily reminder is on and its time, and whether haptics are on.
• A short summary for the widgets (your recent scores and streak), stored in a space on your iPhone that only the Estim8 app and its widgets can read.

We can't see any of it. It may be included in your iPhone's own backups (iCloud or your computer), which are handled by Apple under your backup settings. Deleting the app deletes this data from your iPhone.

Notifications

The daily reminder is optional and off until you allow it. It is scheduled on your iPhone; no server is involved.

Sharing

Nothing is shared unless you tap Share result. You then choose where it goes with the standard iOS share sheet. The shared card and text contain your scores, not your guesses or the answers.

Third parties

The app contains no third-party code for advertising, analytics, crash reporting or tracking, and makes no network requests. Apple may provide us with anonymous, aggregated App Store and crash statistics if you have chosen to share them with app developers in your iPhone settings; that is governed by Apple's privacy policy.

Children

Estim8 is suitable for all ages. Because it collects no data from anyone, it collects none from children.

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
