No app URL, account, credential, or payment detail is collected here.
The product landing stores only bounded pseudonymous page and button events. Gumroad applies its own checkout and privacy terms after an external product-page redirect.
What is stored here
Event type, page path, acquisition class (organic search, referral, direct, or internal navigation), timestamp, and keyed one-way hashes derived from the server-observed network address and browser agent. Raw IP addresses and browser agents are not written to the FlowProof database.
Retention and deletion
Validation rows are removed after 30 days and hard row caps prevent unbounded storage. Clearing the browser cookie does not create another independent confirmation. To request early deletion or ask a privacy question, use the site operator contact page. Because no email or account identifier is collected here, include the approximate visit time and browser used; the operator may be unable to identify a row without retaining more personal data.
What is not happening here
No customer browser run, login, crawl, real payment processing, automated outreach, or cross-site profiling occurs on this server. A purchase can occur only on the explicitly linked Gumroad product page.
