Cepho ("we", "us") operates cepho.cloud and the Cepho mobile app and VS Code/Cursor extension. This policy explains how we process personal data under the GDPR.
Account
Email address, display name, Firebase authentication identifiers, account creation date.
Project data
Files and file contents you sync to Cepho cloud, chat messages and AI responses, sync metadata (file paths, timestamps, snapshot identifiers). This data is stored in Firebase Storage and Firestore.
Beta program
If you participate in the Cepho beta, we collect: usage counters (messages sent, messages remaining), beta status flag, and approximate country/region derived from your IP address at registration time. We do not store your precise IP address.
Waitlist and share campaign
Email address submitted to our waitlist. If you participate in our share campaign, we collect your email address and the link to your post.
Download tracking
We log anonymous download clicks on beta app distribution pages (no personal data, only timestamp and approximate country).
Billing
Payment status and subscription tier via Stripe. We do not store full card numbers — Stripe handles all payment processing.
Technical
Device type, app version, extension version, crash information if you submit feedback.
Cookies
Essential session cookies on cepho.cloud only. No advertising trackers, no third-party analytics.
We process data to provide cloud sync, AI chat, billing, and support (contract / legitimate interest). Beta and waitlist data is processed on the basis of your consent at sign-up. Marketing emails only with consent.
You retain full ownership of your code and files. Cepho is a sync and interface layer — we do not claim rights to your content. We are not responsible for the content, quality, security, or licensing of code you upload. Do not store unlawful material, secrets, or credentials in your Cepho workspace.
When you use Cepho AI chat, your messages and relevant file contents are sent to Anthropic's Claude API to generate responses. Anthropic processes this data as a sub-processor on our behalf. See Anthropic's privacy policy at anthropic.com/privacy.
Where sub-processors are based outside the EEA, we rely on Standard Contractual Clauses or equivalent safeguards.
Account and project data: retained while your account is active. After account deletion we purge cloud data within 30 days unless law requires longer retention.
Beta data: retained until the beta program ends or you request deletion.
Waitlist data: retained until the waitlist closes or you request removal.
Chat history: all messages are retained in Firestore until account deletion. Free-tier users are limited by monthly message quota, not by history duration.
You have the right to access, rectify, erase, port, restrict processing of, and object to processing of your personal data. To exercise any right, contact support@cepho.cloud. Response within 30 days.
You may also lodge a complaint with Datatilsynet (the Danish data protection authority) at datatilsynet.dk.
