Ads privacy
Without your permission, this site counts visits and sign-ups only in aggregate, using the six link parameters of our own posts and ads, with no cookie or advertising identifier. Ads measurement goes further, and it runs only after you choose Allow ads measurement.
What ads measurement does
- Your choice is kept in two first-party cookies for up to 90 days. They hold no advertising identifier until you allow ads measurement on a visit from one of our ads.
- On such a visit we keep the click ID the ad platform added to the link (for example gclid or fbclid), encrypted, for at most 90 days. We never keep TikTok's click ID (ttclid).
- When you join a waitlist, confirm your address, pre-order, or buy, we report that event to the ad platform of the ad you came from, with the click ID (if we kept one) and, once you confirm a waitlist address, a SHA-256 hash of that email address.
- If you came from a Meta, Google, or TikTok ad, that one platform's measurement tag may also load in your browser after you allow it; it reports only page views and button clicks. No tag loads on a visit from any other ad or from no ad, and the other platforms receive reports from our server only.
- We never store your IP address, browser user agent, or the full page address for ads measurement, and we never upload customer lists.
Data categories
- The ad platform click ID, encrypted at rest.
- A SHA-256 hash of your email address. A hash is still personal data: an ad platform that already knows your address can match it.
- The event name and time, and the order value for a purchase or refund.
- The ad, ad group, and campaign you came from.
Who receives it
Only the platform of the ad you came from receives your events. The seven platforms we advertise on are:
- Meta Platforms (Facebook and Instagram ads)
- Google (Google Ads)
- TikTok (TikTok Ads)
- LinkedIn (LinkedIn Ads)
- X (X Ads)
- Microsoft (Microsoft Advertising)
- Reddit (Reddit Ads)
How long it is kept
- Click IDs: deleted 90 days after you allowed ads measurement, or at once when you withdraw.
- Reports not yet sent: deleted 90 days after they were created.
- Sent reports: deleted 30 days after sending; email hashes inside them 90 days after they were created.
Withdrawing
Open Ads privacy settings at the bottom of any page and choose Decline. We delete the stored click ID, stop every report not yet sent, and remove the measurement cookie. Reports already sent are handled under the receiving platform's own policy. Aggregate counts that contain no identifier are kept.
