The handshake.

You must be old enough to use online services in your region. Parents or guardians can request removal of a minor's account.

Collection, deck, location, and note data belong to you. Export and deletion paths are product requirements, not premium perks.

Do not harass people, impersonate others, attack the service, scrape at abusive rates, or resell access to data feeds.

Prices are informational estimates, never offers, appraisals, financial advice, or a promise that a retailer will honor a number shown here.

Some outbound buy links may become affiliate links. If that happens, your price should not change, and the disclosure belongs here.

Material terms changes should be announced with advance notice. Informal resolution comes first when something breaks.
