Never collected

What we don’t have

Not hidden, not anonymized, not “kept securely”: never collected in the first place.

  • Your name or date of birth
  • Identity documents or selfies
  • Your personal phone number, unless you forward calls to it
  • Your IP address in our web logs
  • Analytics, ad trackers or tracking cookies
  • Your location or contacts

  • End-to-end encrypted history

    Texts and voicemail readable only in your browser — not by us.

    Download your history, or wipe it, in one click.

  • Close the account

    From your security settings: everything linked to you is deleted at once.

Questions

Data questions

All questions & answers

Why do you keep billing records for 12 months?

Outgoing calls and texts are paid from your balance, so we need the date, duration and cost of each one to account for it — and to answer you if you question a charge. The content of the call or text is not part of that record.

Can you read my texts?

Only while they are stored, and only if you keep a history. Choose “none” and texts are forwarded without being kept, or turn on end-to-end encrypted history so they can only be decrypted in your browser.

What happens to my data when I close my account?

It is deleted at once: sign-in methods, sessions and balance history. Top-up records stay in our accounting without any link to you, and billing records of outgoing calls and texts are kept until their 12 months have passed.
