Who is responsible for your data
The data controller for Knotworth (getknotworth.com) is Itzhak Fuhrman, trading as Waverine Marketing, Israel. Contact for anything in this policy: hello@getknotworth.com.
1. What we collect
Account data - name and email, via our sign-in provider (Clerk). Buyer profile - the mission, budget, location, and preference answers you give in onboarding, used solely to tailor your analyses. Boat research - the listing URLs you submit, listing text you paste in yourself (kept so your report can be recomputed), the analyses we compute, seller answers you log, and your decisions. Payment records - payment status and amount from Polar; card details never touch our systems. Basic technical data - logs needed to run and secure the service.
2. How we use it
To run the product you asked for: computing pre-checks and reports, generating seller questions, recomputing when you log answers, and showing your dashboard. We do not sell your data, and we do not build a catalog from the listings you research - listing pages are fetched on demand, per boat, for you, and fetched listing text is not retained beyond what the report needs. Listing text you paste in manually is stored with your boat, since there is no page for us to re-fetch; it is covered by the same deletion rights as the rest of your research.
3. Processors we rely on
Clerk (authentication), Convex (database and backend), Polar (payments, as merchant of record), Vercel (hosting), Anthropic (AI text analysis of listings you submit), Jina and Bright Data (fetching the listing page you submit - which one is used depends on the site), and Google (Tag Manager, which loads our measurement tags, and Analytics, which measures site usage once you have accepted analytics cookies). Each receives only what its role requires. We never send Google your email, your account ID, or the listing URLs you research. Separately from Google, we keep a first-party log of product events (which step of the pre-check and checkout a signed-in user reached, and the category of any failure) so we can diagnose problems; it never contains listing URLs or free text and is not shared with third parties.
4. Legal basis & retention
We process your data to perform our contract with you (running the service you signed up for) and on our legitimate interest in securing and improving it. Your research and profile stay until you delete them or your account; payment records are kept as long as accounting law requires.
5. Your rights
Under the GDPR (and similar laws) you can request access, correction, export, or deletion of your data, and object to or restrict processing. Email hello@getknotworth.com and we'll act on it promptly. You can also complain to your local supervisory authority.
6. Cookies
We use cookies that are strictly necessary for sign-in and session security, plus a small cookie that records your own cookie choice. With your agreement we also set analytics cookies from Google Analytics, loaded through Google Tag Manager, which tell us how the site is used in aggregate. Analytics stay switched off until you accept them, declining costs you no functionality, and you can change your mind at any time from the Cookie settings link in the footer. We do not use advertising, profiling, or cross-site tracking cookies, and we do not sell or share what analytics collects.
7. Changes
Material changes to this policy will be announced in-product before they take effect.
