Fernweh Lab ("we", "our", or "us") operates the KeyStash: Şifre Kasası mobile application. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.
KeyStash is designed as a local-first, offline password manager. All your passwords, accounts, and credentials are encrypted using industry-standard local cryptographic protocols and stored strictly on your device. We do not operate any cloud databases, and your sensitive credentials never leave your device.
The App utilizes your device's secure native biometric capabilities (fingerprint or facial recognition) for secure access. Biometric data is handled entirely by your operating system's secure hardware enclave. The App does not collect, access, or store your biometric data.
To keep this application free, KeyStash integrates Google AdMob to display banner advertisements. Google AdMob may collect and use device identifiers (such as Advertising IDs) and technical logs to serve relevant ads, prevent fraud, and analyze ad performance. Google's use of this data is governed by the Google Privacy Policy.
Our Service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from anyone under 13 years of age.
We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes.
If you have any questions about this Privacy Policy, you can contact us via our developer platform.
