Select originals, verify, then seal.
Files are encrypted in small browser chunks without compression, conversion or previews. Keep originals until cross-device recovery also succeeds.
This invitation trial stores one copy on a single host, without an independent copy. A host disk failure may lose files. Retrieval is free for 90 days. Keep another source of your originals.
1. Select files
Up to 50 files, 25 MB each and 250 MB per package. Only a small signature is read for checking. Phone pickers may create temporary files; zero free space cannot be supported reliably.
Trial packages are destroyed 90 days after sealing. Retrieval remains free until destruction, even if invitations end. Unsealed sessions expire after 24 hours idle or 48 hours total.
2. Unlock locally
Only a non-extractable device signing key stays in this browser for reuse. Recovery codes and vault decryption keys are never stored here. Clearing site data requires registering this device again.
3. Encrypt, read back, seal
This browser cannot safely save retrieved originals in chunks, so storage cannot start here. Use a verified browser with directory write support. Selecting files alone does not prove safe retrieval.
The service cannot preview photos and never deletes photos from your phone. Check your device first →
