Privacy Policy

Overview

Contexer is an open-source context engine for AI coding agents. We respect your privacy and collect as little data as possible. This policy explains what we collect on contexer.ai, why, and the rights you have under the EU General Data Protection Regulation (GDPR), the UK GDPR, and similar laws.

Data controller

Contexer.ai acts as the data controller for personal data processed via this website. Contact: hello@contexer.ai.

Data we collect

• Waitlist signups: email address and, optionally, name, team size, and a short free-text note about your context-management pain point. Stored to send product updates and early-access invitations.
• Technical metadata: referrer and user-agent string at the moment you submit the waitlist form, used to prevent abuse and understand traffic sources.
• Analytics (with consent): aggregate page views and approximate region. No cross-site tracking or advertising identifiers.

Self-hosted use of the Contexer open-source software transmits no data to us.

Legal bases (GDPR Art. 6)

• Consent — waitlist signup and analytics cookies.
• Legitimate interest — operating the site, security, and abuse prevention.
• Legal obligation — responding to lawful requests from authorities.

Retention

Waitlist data is kept until launch and for up to 24 months after, or until you ask us to delete it. Server logs are retained for up to 30 days.

Sub-processors

We use the following providers to operate the site. They process data on our behalf under data processing agreements:

• Supabase — database hosting (EU region) for the waitlist.
• Cloudflare — CDN, edge hosting, and DDoS protection.

Where data is transferred outside the EEA/UK, we rely on the EU Standard Contractual Clauses and the UK International Data Transfer Addendum.

Your rights

If you are in the EEA, UK, or Switzerland you have the right to access, rectify, erase, restrict, or port your personal data, and to object to processing. You may also lodge a complaint with your local supervisory authority. To exercise any of these rights, email hello@contexer.ai.

California residents have analogous rights under the CCPA/CPRA. We do not "sell" or "share" personal information as those terms are defined under California law.
