Privacy

Cenblu is a small paid board. We collect only what we need to run the auction, show the board, and contact the person who paid.

What we store

• The public X post id, canonical URL, embed markup, and—when the X API is configured—public metric snapshots.
• Bid amounts, rank, and Stripe payment identifiers for applied charges.
• The checkout email, stored encrypted, plus a keyed hash used only to recover a management link.
• Anonymous card-view and outbound-open events. Viewer ids are hashed with a daily-rotating salt and are not accounts.

What we do not do

• We do not sell personal data.
• We do not run ads or a tracking pixel for advertisers.
• We do not ask X for private metrics or DMs.
• Click-through rate is withheld until there are enough unique views that a single person cannot be read out of the number.

How long

Raw analytics events are kept for a limited window (default 30 days) and then discarded. Board records and applied bids stay so the archive remains honest.
