How long are photos kept on Snaptide?

Photos are retained until you delete them or your account is terminated, and inactive data may be deleted after a reasonable period per the terms of service. Practically, that means your albums stay put until you remove them — there's no aggressive auto-purge of old work while your account is active. If you want something gone, deleting the album removes it permanently, and account-level deletion is available through the data deletion request route.
