Privacy

last updated 14 October 2026

Caime is messaging that understands the difference between the people in your life. This page says what Caime keeps about you, why, who else sees it, how long it’s kept, and what you can do about it. Caime is run by DATA C OÜ (16589957, Harju maakond, Tallinn, Lasnamäe linnaosa, Sepapaja tn 6, 15551), which is responsible for your data (its controller, in the words of data protection law). Questions about it go to hello@cai.me.

The short version

What Caime keeps

Why

Each of these is one of the grounds data protection law allows (in the GDPR, Article 6):

Caime makes no decision about you by machine alone that has a legal or similarly serious effect on you. What it sorts, suggests or infers is a suggestion you can see the reason for and decline.

Who else sees what

Some of these companies, and Caime’s servers where the hosting provider above says so, are outside the European Economic Area, in countries the European Commission hasn’t found to protect personal data as the EU does. Where your data goes there, it goes under the safeguards the GDPR asks for (Article 46): the European Commission’s standard contractual clauses in each company’s data processing terms, or, for a company in the United States certified under it, the EU–U.S. Data Privacy Framework. Write to hello@cai.me for a copy of the safeguards for any of them. We don’t sell personal data, and we don’t share it for advertising.

How long it’s kept

Your choices, and your rights

Wherever you live, you can ask us what we keep about you, ask us to correct or delete it, object to how we use it, and take it with you. Where data protection law applies (in the EU and the UK, for example), you can also complain to your data protection authority. Write to hello@cai.me and we’ll answer within a month.

Children

Caime is for people 13 and older, from the day they turn 13 where they live, and 18 and older for people who live in Egypt or Saudi Arabia, whose law asks a guardian’s consent for younger people. There, someone younger joins from 13 in Egypt and Saudi Arabia only with their parent’s or guardian’s consent, given in Caime: the parent, on Caime themselves, makes a link for that one child and the child signs up through it on their own device; or the child signs up and their account waits, reaching nothing, while they ask their parent: by the parent’s handle, once they’ve seen who it is, or with a link they send a parent not on Caime yet. Either way the parent agrees on the child’s own account, seeing the date of birth the child gave, which their yes confirms. Someone who says the account isn’t their child’s is never asked again by it, and after three such answers it’s deleted. Caime keeps who agreed, for whom, when and to which words, how it began and how many were asked (never who said no), for as long as the account. A date of birth or a country corrected later follows the same rules: under the youngest age Caime opens there, it isn’t taken; where a parent’s consent is what lets someone in, the account waits for one; and a child their parent looks after asks that parent, whose yes (or a document check that finds them 18 or over) makes the change. Until the child reaches the age where they live, their parent sees whom they’re connected with, never a message, and says yes to each new connection first, whichever of the two asked: a request reaches the other person, or the child, only once the parent has. The child sees who their parent is, what the parent sees, and the requests of theirs that wait. The parent may also choose to say yes to every new way in first: an invitation into a group or a space, an ask to join one, a message request to the child, and the child starting to write to an organization each wait for the parent, who sees who and where, never what anyone wrote; and the child writes first only to people they’re connected with, a connection request asking the parent. The child sees that their parent does, and what waits; the parent can turn it off, and then whatever waited goes on. The parent can withdraw the consent, which deletes the child’s account. A parent who never agrees within seven days, or says the account isn’t their child’s, has it deleted the same way. The rules for people under 18 apply until the day they turn 18. Under 18:

Security

Passwords are kept as salted scrypt hashes, and passkeys as their public keys alone, for the domain Caime is on. Sign-in sessions, recovery codes, access tokens, your calendar’s address, and apps’ tokens, codes and secrets are kept only as hashes; the exception is an organization’s webhook secret, which Caime keeps so it can sign what it sends. Caime is served over HTTPS, so what passes between your device and Caime is encrypted in transit. The keys of private conversations are made on your devices and never leave them. No system is perfect: if you find a weakness, please tell us at hello@cai.me. If a breach of Caime’s security puts your data at risk, we’ll tell you what happened, what it touched and what to do, without undue delay, and tell the authority as the law requires.

On your device

On the web, Caime sets one cookie, to keep you signed in, and no advertising or analytics cookies; the phone apps keep your sign-in in the phone’s secure storage. So it opens quickly and works offline, the app keeps what you’ve seen recently on your device: your account details, your inbox, the latest messages in up to 30 conversations, your people, actions and notifications, and messages, drafts and actions still waiting to be sent. Of a private conversation it keeps only messages that are still sealed. Signing out removes all of this from that device, and on the web asks your browser to clear the photos and files it kept. If you’re signed out from another device, all of this goes the next time Caime is opened on that device with a network; until then, it opens on what it kept. On the web, Caime also keeps its own files (never your messages) so it can open without a network.

Changes

When this page changes, its date above does. For a change that matters, we’ll say so here before it applies.
