Frequently asked questions
How does Notebond work?
Messages and attachments are encrypted on your iPhone (AES-256) before you send them by email or any messaging app. Only the recipient can open them. Our servers only handle the keys that unlock each message, never the message itself.
My recipient doesn't use Notebond. Can they still open my message?
Yes. Set a password for the message and share it with them however you like, for example by phone or in person.
What's the difference between Free and Pro?
- Free: 5 secure sends a month. Invite friends for 5 extra sends each month for every friend who joins (up to 20 sends a month in total).
- Pro: unlimited sending, the encrypted Vault, and up to 5 devices.
How do I manage or cancel my subscription?
Subscriptions are handled by Apple: on your iPhone, go to Settings → [your name] → Subscriptions. Deleting your Notebond account does not cancel your subscription; cancel it with Apple as well.
How do I delete my account?
In the app, go to Settings → Account → Delete Account and confirm with your password and Face ID. Deletion is immediate and permanent. The Privacy Policy explains exactly what is deleted.
Can't access the app? Email support@sendbond.com from the address your account is registered with, and we'll delete it for you. Accounts managed by a company are deleted through that company's administrator.
Why can't I open a message any more?
To protect your privacy, the key for each message is deleted 24 hours after the message is first opened, or 60 days after it was sent if it's never opened. After that, nobody (including us) can open it. Save anything you want to keep to your Vault before then.
