Who we are
Tlon OÜ is an Estonian company, registry code 17354127, registered address Sepapaja tn 6, 15551 Tallinn, Estonia. For privacy matters write to contact@tlon.sh. Tlon OÜ is the data controller for personal data processed through this website and our corporate communications.
Data we collect on tlon.sh
This site is a static marketing site. We use Vercel Analytics and Vercel Speed Insights to measure aggregate traffic and performance. Both are configured to operate without cookies and without collecting IP addresses or personally identifying information. We do not run advertising trackers. If you email us, your message and email address reach us via our mail provider and are retained for correspondence and record-keeping.
Data in our products
Our first-party products are designed to minimise data collection. Think runs language models entirely on your device; it does not transmit prompts, conversations, or model outputs to Tlön or to any third party. matchiful processes the account information you provide (name, email, activities, matches) on our backend strictly to operate the service. Product-specific privacy notices are published inside each product and on its listing page where applicable.
Legal basis and your rights
We process personal data under GDPR on the bases of contract (where you use a product), legitimate interest (aggregate site analytics, security), and consent (where required). You have the right to access, correct, export, and delete your personal data, and to lodge a complaint with the Estonian Data Protection Inspectorate (aki.ee). To exercise these rights, email contact@tlon.sh.
Retention and transfers
We retain personal data only as long as needed for the purpose it was collected or as required by Estonian and EU law. Our infrastructure providers may process data in the EU and United States under Standard Contractual Clauses and the EU-US Data Privacy Framework.

We will post updates to this policy on this page. Material changes will be dated above.
