Privacy policy
Lumen is self-custodial: your keys are generated and stored on your device, and we never have access to them or your funds. We collect minimal data — basic app analytics and crash reports — to keep the app working, anonymised where possible.
What we never collect
- Your seed phrase or private keys
- Custody of your assets
- More personal data than the app needs to function
Terms of use
Lumen provides software to access public blockchains. You are responsible for safeguarding your recovery method and for the transactions you sign. The app is provided "as is," without warranty of any kind.
Acceptable use
Use Lumen lawfully and at your own risk. We may update the app and these terms; continued use constitutes acceptance.
Self-custody
Because only you hold your keys, only you can recover your wallet. If you lose your device and your recovery method, your funds cannot be restored by us or anyone else. Back up your recovery to your own cloud or hardware, and keep it safe.
