Privacy notice
Last updated 11 November 2026
This notice covers the Twofold website: the free tone check, the waitlist and the contact form. The Twofold app isn't open yet. It will have its own, fuller privacy policy when it launches.
The free tone check
- The message you paste is sent to our language-processing providers (Lovable, which passes it to OpenAI) only to write your check. We ask them not to store it, and Twofold never saves it.
- To keep the check free, we count checks per connection for 24 hours. We store only a scrambled (hashed) version of your internet address and the time, never the address itself or your message.
- Please leave out bank details and anything you wouldn't want processed this way.
The waitlist
- Your email address.
- Your country, if you choose one.
- Any optional answers you give, such as whether your co-parent is likely to join, or your profession if you request professional access.
- Where you came from: campaign tags in the link you followed and the referring website, if your browser shares it.
We use these to contact you about Twofold's launch and your place on the waitlist, and to understand, in total, how people find us. We keep them until Twofold launches plus 12 months, or until you ask us to delete them, whichever comes first.
The contact form
Your name, email address and message, so we can reply. We keep them for 12 months after our last reply.
Who processes it
Lovable hosts the website, and its cloud database (run on Supabase) stores the waitlist and contact messages. Lovable and OpenAI process tone checks as described above.
We never sell it
We never sell or rent your details, and we don't share them with advertisers. This site uses no advertising trackers.
Asking us to delete it
Send us a message through the from the email address you signed up with, and we'll delete your details and confirm when it's done.
