Facts Memorizer privacy policy
Facts Memorizer collects no personal data; everything stays on your device.
Effective date: 9 November 2026
Previous version (effective 19 August 2026)
Short version: Facts Memorizer does not collect, transmit, or share any personal data. It has no servers and makes no network requests at all. Everything the app knows about you — which times tables you have practised, how you answered, how fast — is stored only on your own device. There are no accounts, no analytics, and no ads.
Data we collect
None. Facts Memorizer has no servers and makes no network requests, so there is nothing for it to send anywhere. The app does not ask for your name, email, age, or location, it has no sign-up and no login, and it requests no device permissions — no camera, no microphone, no contacts, no location. It uses no analytics, advertising, or crash-reporting services of any kind.
Data stored on your device
You do not enter any content into Facts Memorizer. You choose which times tables to practise and how, and the app records how the practice went so it can show you your own progress. That record is kept in a local database on your device:
| Data | Purpose | Leaves your device? |
|---|---|---|
| Your answers to each question | Work out which facts you find hard, and show your accuracy and speed over time | No |
| Your practice sessions | Show a summary at the end, and keep your best results per game mode | No |
| Your settings | Remember your language, theme, sound and the rest of your preferences | No |
The questions themselves are generated by the app from the times tables you pick — nothing is downloaded, and there is no content for you to create or upload. All of this data is removed if you delete the app, and none of it is ever synced, backed up to a server, or made accessible to us or to anyone else.
Third parties
Facts Memorizer does not integrate with any third-party service — no analytics SDKs, no advertising networks, no social logins. Nothing about your use of the app is shared with anyone.
Links that open outside the app
The app may offer to open a page — this policy, for example — in your device’s own browser. This policy is published on João David Silva’s own website, joaodavidsilva.com, which has its own privacy notice covering visits to the site. Any other link takes you out of Facts Memorizer to a site we do not control, and that site’s own privacy policy applies from that point on. The app tells the browser nothing about you when it does this.
Children’s privacy
Facts Memorizer is built for children to use, and it collects no personal data from anyone — so there is none to collect from a child either. There is nothing to sign up for, no way to contact another person through the app, and no advertising.
Changes to this policy
If this policy ever changes — for example, if a future version of the app adds a feature that handles data differently — this page will be updated and the effective date above will change accordingly.
