Privacy Policy

The NeonMind app (book summaries) collects the minimum data needed to work.

What we store

• A device identifier that the app itself generates on first launch, and your chosen language. Your progress, notes, reviews and goal are stored against it.
• Name, age group and interests, if you entered them on first launch. The name is shown under your reviews; interests order the shelves on the home screen.
• Usage statistics: which books you opened and finished and how much time you spent in the app. They power the goal, streaks and the Profile tab.
• Subscription: when you subscribe we receive a signed transaction confirmation from Apple (no card data) and store the subscription expiry.

What we do not do

We do not sell or share data with third parties, show ads, or use trackers or advertising identifiers. Data is stored on our servers in the EU (Hetzner, Germany).

Deleting your data

In the app: Profile → “Delete my data” removes everything at once. Or email sapa4tech@gmail.com from the device with the app installed. Without the device identifier the data becomes anonymous and is deleted after 12 months of inactivity.
