Privacy policy
Last updated: 21 May 2026
1. Introduction
ObserverKit is operated by Undefined Computer (full identification in our Legal notice). Undefined Computer operates as both a data controller and a data processor depending on the context. We are the data controller for personal data you provide when creating and managing your ObserverKit account. When you use ObserverKit to collect error events from your own applications, we act as your data processor for any personal data contained in those events. The terms governing that processing are set out in our Data Processing Agreement (DPA), which is incorporated by reference into our Terms of Service.
2. Personal data we collect as controller
- Account data: email address and display name.
- Billing data: payment processing is handled by Stripe. We store only your Stripe customer ID; we do not store full card numbers or bank details.
- Support correspondence: messages you send to us via email or support channels.
- Server logs: retained for security and abuse prevention only. Logs contain IP address and HTTP request metadata; they are not used for marketing or profiling.
3. Legal bases (RGPD art. 6)
- Contract (art. 6(1)(b)): account creation, service delivery, and billing.
- Legitimate interest (art. 6(1)(f)): security logs and fraud prevention.
- Consent (art. 6(1)(a)): any opt-in marketing or newsletter emails.
- Legal obligation (art. 6(1)(c)): invoicing and accounting records.
4. Retention
Account data is retained for as long as your account is active. Upon account closure, your personal data is deleted within 30 days. Backup copies are retained for up to 30 days after deletion before being permanently purged.
5. Recipients & subprocessors
We share personal data only with the subprocessors necessary to deliver the Service. A full list of subprocessors, including their country of establishment and the safeguards in place, is available on our Subprocessors page.
6. International transfers
Hosting and database storage are provided by Hetzner Online GmbH (Germany) within the European Economic Area, in a data center located in Helsinki, Finland. Some of our other subprocessors are based outside the European Economic Area: Resend Inc. (email delivery, US) transfers data to the United States under Standard Contractual Clauses. Visitors Now LLC (website analytics, US) processes only anonymous, aggregated data and stores it on EU-hosted infrastructure; no personal data is transferred. Full details are on our Subprocessors page.

This tool is cookie-less, collects no personally identifiable information, and stores aggregated data on EU-hosted infrastructure. It qualifies for the CNIL exemption applicable to cookie-less audience measurement tools that collect no personal data and do not enable cross-site tracking.
