Privacy policy.

When you take a reading, the app saves the two first names you typed, the score, and the result to a file inside its own storage on your device. That file is what powers the Past Reads list.

That data:

• stays on your device
• is not transmitted anywhere, because the app makes no network requests of its own
• is not shared with us or with anyone else
• is deleted when you delete the app, or when you clear it from inside Past Reads

• It does not read your fingerprints. iPhones do not make fingerprint data available to apps, and Thumbsparks never has access to it. The thumbprints on screen are targets to aim at.
• It does not use the camera, the microphone, your contacts, your photos, or your location.
• It does not track you, across this app or any other.
• It does not show advertising.
• It does not use analytics of any kind.

During a five-second reading the app watches where the two thumbs are on the glass, how large each contact patch is, and how steadily the phone is held. Those readings are used to calculate the score and are discarded immediately afterwards. They are never stored and never transmitted.

Thumbsparks Extreme is a one-time purchase handled entirely by Apple. We never see your payment details. Apple's own privacy policy covers that transaction, and the App Store is the only network connection involved in using the app.

Thumbsparks is rated 12+ and is not directed at children under 13. Because the app collects no data at all, there is nothing for us to collect from a child or from anyone else.

If this policy ever changes, the date at the top of this page will change with it. Continued use of the app means you accept the updated policy.
