# Calkillator Privacy Policy (English)
**Last updated: 2026-07-28**
Calkillator ("the App") does not collect any personal data.
## 1. Data We Collect
None. The App does not operate any backend server and does not collect, store, or
transmit any personally identifiable information (name, email, location, advertising
identifiers, etc.).
## 2. Microphone & Speech Recognition
The App requests microphone access solely to let you enter calculations by voice. Audio
is processed in real time by the operating system's own speech recognition service
(Apple's Speech framework on iOS, or the Android speech recognition API) purely to
convert speech to text. The App's developer does not store or transmit any audio data.
Processing by the OS speech recognition service is governed by Apple's / Google's own
privacy policies.
## 3. In-App Purchases
The "Calkillator Minions" purchase (unlocks voice input and PRO features, $0.99,
non-consumable) is processed entirely by the Apple App Store or Google Play billing
system. The developer never accesses or stores payment information; billing is governed
by the respective store's privacy policy.
## 4. Data Stored On Your Device
Settings such as language preference and purchase/unlock status are stored locally on
your device only and are never transmitted. Deleting the app deletes this data.
## 5. Export / Share Log
The "Export" / "Share" feature in Settings only runs when you trigger it, and the
generated file is delivered only to the destination you choose (Files app, Messages,
etc.). The developer has no access to this data.
## 6. Third-Party Sharing
The App contains no advertising, analytics, or tracking SDKs, and does not share any
personal data with third parties.
## 7. Children's Privacy
The App does not knowingly collect personal data from children under 13.
## 8. Contact

## 9. Changes
This policy may be updated as app features change; the "Last updated" date above will
reflect any revision.
