Privacy Policy
Effective July 23, 2026
What Gumwall is
Gumwall is an iOS app where friends save and share memories — photos, captions, dates, and optional places — on each other's walls. This policy explains what we collect and how it's used.
Information we collect
- Account info: your phone number (used to sign in with a one-time SMS code), first and last name, and an optional profile photo and birthdate.
- Memories you create: photos, captions, memory dates, optional place tags, and an optional weather snapshot for the memory's time and place.
- Friend tags: when you tag a friend, we store the name and phone number you provide so the memory can appear on their wall. If they're not on Gumwall yet, they may receive a one-time SMS invite.
- Contacts (optional): if you allow contact access, it's used only to help you pick a friend to tag. Your address book is never uploaded or stored.
- Location (optional): if you allow location access, it's used only to suggest nearby places while tagging a memory. We don't track your location in the background.
- Device info: a push notification token if you enable notifications.
How we use it
- To operate the app: sign-in, storing and showing memories, sharing them with tagged friends, and sending notifications you've enabled.
- To manage Gumwall Premium subscriptions (purchases are processed entirely by Apple).
- We do not sell your personal data, and we don't use it for third-party advertising.
Who processes data for us
- Supabase — database, authentication, and photo storage.
- Twilio — delivers sign-in codes and invite texts by SMS.
- Apple — payment processing and push notifications.
- RevenueCat — subscription status management (receives an anonymous user ID, never your phone number or name).
- Open-Meteo — weather lookups using approximate memory coordinates only; no account data is sent.
Sharing between users
Memories are shared only with the friends involved: the creator and anyone tagged. There is no public feed. Memory links you share yourself (gumwall.com links) are viewable by anyone who has the link.
Data retention & deletion
Your data is kept while your account is active. You can delete your account any time in the app under Profile → Delete Account, which permanently removes your profile, memories, photos, tags, and notifications. You can also email us at upperleftstudioaz@gmail.com to request deletion or a copy of your data.
Children
Gumwall is not directed at children under 13, and we don't knowingly collect data from them. If you believe a child under 13 has an account, contact us and we'll delete it.
Changes
If this policy changes materially, we'll update this page and the effective date above.
