Privacy Policy
Last updated 11 November 2026
The short version: Yenkai keeps the photos you add to a book so the people in that book can see and save them. We don't sell your data, we don't show ads, and you can delete your account from Profile at any time.
Who we are
Yenkai is a shared photo book app made in Accra, Ghana. "We" means the people who make Yenkai. You can reach us at hello@yenkai.app.
What we store
- Your account: your email address and the display name you choose.
- Your books: titles, covers, pages, and what you place on them (photos, stickers, notes), with who added what and when.
- Your photos: the original file you add, a lighter copy for showing on pages, and any cut-out you make. We also keep the date a photo was taken so Memory Lane can sort it.
- Invites: the email addresses you invite to a book.
- Plus: whether you have Plus and until when. We never see your card details.
Where it's stored
Your account, books and photos, including every original, are stored with Supabase in its EU (London) region. Supabase acts as our processor and stores the data on our behalf.
Signing in
You sign in with a one-time code sent to your email. We send those emails, and book invites, through an email provider that only receives the address and the message.
Who can see your photos
Only the members of the book you add them to. Any member can view a photo and save the original. People you remove from a book lose access to it.
Payments
Plus is sold through the Apple App Store, Google Play or Lemon Squeezy. They handle the payment and tell us only that your Plus is active and when it ends. Their own privacy policies apply to what you give them.
The waitlist
If you join the waitlist on this website, we keep your email address to tell you when Yenkai opens. Ask us at hello@yenkai.app and we'll remove it.
Deleting things
A photo you delete from a page can be restored for 30 days, then it's removed for good. To delete your account, go to Profile in the app and choose Delete account: your account and the photos you added are deleted.
Your rights
You can ask for a copy of your data, ask us to correct it, or ask us to delete it. Email hello@yenkai.app and we'll reply within 30 days.
Children
Yenkai isn't meant for children under 13, and we don't knowingly collect their data.
Changes
If we change this policy in a way that matters, we'll tell you in the app or by email before it takes effect.
