privacy

we built Plus1 so your group's context stays yours. inside Plus1, we don't store raw phone numbers — we use salted one-way hashes for identity, so even our own database can't tell you who's in a thread. when the people in a group change, that group's memory doesn't follow anyone across other chats.

to generate replies, messages sent to Plus1 are processed by third-party AI providers (for example OpenAI or Anthropic) under their contractual data-use terms. we don't send them raw phone numbers. we don't sell your messages. we use message content to run and improve Plus1; if that ever changes in a material way, we'll update this page before it does. messages also pass through SMS/MMS carriers (T-Mobile, AT&T, Verizon, etc.) on their way to and from your phone — carriers have their own data practices for message delivery.

we keep messages only as long as we need them to run the product, and we design to minimize what could be disclosed even if we're asked. STOP removes you from Plus1 in any chat, any time.

this page is a plain-language summary. we'll publish a fuller policy before we charge money or scale.
