This Privacy Policy describes how the "n of m" application ("the App") handles your information. The App implements Shamir's Secret Sharing for splitting and recovering seed phrases. Your privacy is fundamental to the App's design.
The App does not collect, transmit, or store any personal data on external servers.
Specifically, the App does not collect:
All data generated by the App -- including seed phrases, secret shares, vault configurations, and encryption keys -- is stored exclusively on your device using the browser's local storage or the device's native storage.
No data ever leaves your device unless you explicitly choose to export it (e.g., printing share cards, saving PDF files, or exporting vault backups).
The App may request access to your device's camera solely for the purpose of scanning QR codes during share recovery. Camera data is processed entirely on-device and is never recorded, stored, or transmitted.
The App does not integrate with any third-party analytics, advertising, or tracking services. No data is shared with third parties.
When you use the vault feature, your data is encrypted locally using AES-256-GCM with a password you provide. The encryption and decryption occur entirely on your device. Your password is never stored or transmitted.
The App is not directed at children under the age of 13 and does not knowingly collect any information from children.
This Privacy Policy may be updated from time to time. Any changes will be reflected on this page with an updated revision date. Continued use of the App after changes constitutes acceptance of the revised policy.
If you have questions about this Privacy Policy, please open an issue on the App's GitHub repository.
