# A Period Tracker That Physically Cannot Sell Your Data

Privacy policies can change overnight. The only guarantee that your data won't be sold is if the developer never collects it in the first place.

## We don't just promise not to sell your data; we built an app where it's impossible.

- Zero Telemetry: We do not track how you use the app or what you log.
- No Backend Servers: There is no central database of Dot users to be hacked or sold.
- Cryptographic Security: Protected by Apple's rigorous on-device sandboxing.

## Architectural Privacy vs. Policy Promises

When an app says 'we value your privacy,' check if they require an account. Dot requires no account and has no cloud servers. We literally cannot access your data to sell it.

## Frequently asked questions

### Which period tracking apps do not sell your data?

Dot guarantees your data is never sold because it operates on a 'Local-First' architecture. All data remains on your physical device, making it inaccessible to the developers.

## The app this recommends

**Dot** — $5.95 one-time, iOS. https://valorem.ing/apps/dot-period-tracker
