Privacy policy

Last updated: November 11, 2026

RelationOS is a private address book that you can question in plain language. This policy explains what data RelationOS (“we”) handles when you use it, why, and the control you keep over it.

The short version

  • Your network belongs to you. We do not sell it, share it or advertise against it.
  • We do not use your data to train AI models, and neither do our providers.
  • Access to your Google account is read-only and limited to what is listed below.
  • Deleting your account erases all of your data immediately.

Data we handle

Account. When you sign in with Google we receive your name, email address and profile picture, to create your account.

Google data, if you connect it. Connecting is a separate, optional consent. With your permission we read:

  • your Google contacts, including “Other contacts” Google saved automatically: names, email addresses, phone numbers, job title, company, location, photo and notes;
  • your Google Calendar events: title, date and attendees of past meetings, to know who you meet and when. Event descriptions and attachments are not stored;

We never send email, create events, or change or delete anything in your Google account.

Other sources you add. Files you upload (LinkedIn export, phone contacts, Facebook or Instagram exports) and, if you install our browser extension, your LinkedIn connections and their public profile details, read from your own logged-in LinkedIn session.

What you write. Notes, reminders, groups, links between contacts and your conversations with the assistant.

Technical data. Minimal server logs (errors, timings, token counts of AI requests) without the content of your contacts.

How we use it

  • to build and display your network, merge duplicates and score how close you are to each person;
  • to answer the questions you ask the assistant and to prepare the changes and drafts you request;
  • to keep the service secure and working.

We do not use your data for advertising and we do not build profiles for third parties.

Google user data: Limited Use

RelationOS’s use and transfer of information received from Google APIs to any other app adheres to the Google API Services User Data Policy, including the Limited Use requirements. In particular, Google user data is used only to provide the features described here, is not transferred to others except as needed to provide those features, is not used for advertising, is not used to develop or train generalized AI models, and is not read by humans unless you ask us to for support, it is required for security, or the law demands it.

The assistant and AI

When you send a message to the assistant, the relevant parts of your network (names, titles, companies, locations, shortened notes and interaction previews) are sent to Anthropic, our AI provider, to produce the answer. Email addresses, phone numbers and birthdays are never sent. Anthropic processes this data on our behalf and does not use it to train its models. The assistant never changes a contact by itself: every change is proposed to you and applied only when you confirm it.

Who processes data for us

  • Supabase: database and sign-in;
  • Vercel: hosting;
  • Anthropic: AI processing of assistant requests;
  • Google: sign-in and, if connected, the source of your contacts and calendar.

We share data with no one else, unless the law requires it.

Security

Data is encrypted in transit. The tokens that give access to your Google account are encrypted at rest with AES-256-GCM. Browser-extension tokens are stored only as hashes. Every query is scoped to your account.

Retention and deletion

We keep your data for as long as your account exists. You can disconnect Google at any time in Settings, which deletes the access tokens; you can also revoke access from your Google account. Deleting your account in Settings immediately and permanently erases your profile, contacts, interactions, notes, conversations and tokens.

Your rights

You can access, correct and delete your data from within the app. Depending on where you live (for example under the GDPR), you also have the right to obtain a copy of your data, to object to or restrict its processing, and to complain to your data protection authority.

Changes

If this policy changes in a way that matters, we will tell you in the app before the change applies.
