Privacy policy

Data controller

The data controller is lacause (see the legal notice). For any request: lacause.ai@gmail.com.

Data we collect

• Account: your email address (private, never shown publicly), your username (public), and, if you choose a password, its hashed form (never the plaintext password).
• Sign-in via GitHub or Google (optional): the account identifier and verified email provided by the provider.
• Your content: prompts, reviews, votes, bookmarks, reports, and an optional bio.
• Technical data: IP address (used temporarily to limit abuse and spam) and server logs.
• Anonymous analytics (PostHog), only if you consent — see “Cookies & consent”.

Purposes & legal bases

• Provide the service (account, publishing, moderation) — performance of the contract and legitimate interest.
• Security and abuse prevention (rate limiting, moderation) — legitimate interest.
• Sending sign-in emails (magic links) — performance of the contract.
• Anonymous analytics to improve the site — your consent, revocable at any time.

“Improve this prompt” AI assistant

If you use this optional feature, the prompt text you submit is sent to Anthropic's API to be rewritten, then returned. Do not include any personal or confidential data.

Processors & hosting

• Vercel — application hosting (USA; transfer covered by appropriate safeguards).
• Neon — database, hosted in the European Union.
• Resend — sending transactional emails (sign-in links).
• Upstash — anti-abuse rate limiting.
• Anthropic — only if you use the AI assistant (see above).
• PostHog — anonymous analytics, in the EU, only with your consent.

Retention

Your account data is kept as long as your account exists. On deletion, your contributions are anonymized (decoupled from your identity) and your personal data deleted. Technical logs are kept only for a limited time.

Your rights (GDPR)

• Access & portability: export all your data from “My account”.
• Rectification: edit your profile and content at any time.
• Erasure: delete your account from “My account” (your contributions are then anonymized).
• Objection & consent withdrawal: turn off analytics at any time.
• Complaint: you may lodge a complaint with the competent supervisory authority (in France, the CNIL).

Cookies & consent

Prompedia uses a session cookie (essential for sign-in), a cookie remembering your language, and a cookie storing your consent choice. Analytics (PostHog) is enabled only with your explicit consent and stays anonymous. No advertising, no third-party marketing trackers, no data resale.
