Privacy Policy — Hashido

Last updated: 26 June 2026

Hashido (“the app”) is a logic puzzle game published by Rıza Kagan Terzi. Your privacy matters, and the app is built to need as little of your data as possible.

Summary

• No account, no login. You can use the entire app without signing in.
• Your game data stays on your device. Progress, streaks, daily history and settings are stored locally on your device only. They are never uploaded to us.
• No ads. No tracking. No advertising SDKs.
• We do not sell or share your personal data with anyone.

What data we collect

Data stored only on your device

Puzzle progress, completion times, streaks, the daily-puzzle calendar, and your settings (theme, haptics, sound, reminder preference) are stored locally using Apple’s on-device storage. This data does not leave your device and is not accessible to us.

Anonymous, privacy-friendly analytics

The app may use a privacy-first analytics service (TelemetryDeck) to understand how features are used in aggregate — for example, how often puzzles are started or solved. This data:

• contains no personal information and no advertising identifier (IDFA),
• is not linked to your identity,
• is not used to track you across apps or websites.

If analytics is not configured, no analytics data is sent at all.

Purchases

Premium is a one-time purchase processed by Apple (StoreKit). Apple handles all payment information. We never see or store your payment details.

Notifications

The optional daily reminder is a local notification scheduled on your device. There is no push server and no account involved. It is off by default and only works if you enable it in Settings.

What we do NOT collect

• No name, email, phone number, or contacts
• No location
• No advertising identifier (IDFA)
• No cross-app or cross-site tracking
• No third-party advertising

Children

Hashido is suitable for all ages and collects no personal data, so it is safe for children to use.

Your rights (GDPR / KVKK)

Because we do not collect or store your personal data on our servers, there is nothing for us to access, correct, or delete on your behalf. You remain in full control:

• Delete all data: Settings → “Delete all data” permanently removes all locally stored progress, streaks, and settings.
• Stop analytics: analytics is anonymous and aggregate; you can also disable it at the system level.

Under the EU GDPR and Türkiye’s KVKK, you have the right to access, rectify, and erase personal data. Since Hashido stores everything on your device and collects no personal data, you can exercise these rights directly within the app.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new “Last updated” date.
