Frequently Asked Questions
Do I need an account?
No. You can start right away without one. If you use Sign in with Apple, you can recover everything on a new iPhone. You can also link Apple later from Profile.
I changed iPhone and my sizes are gone
Your data can only be recovered on a new iPhone if Sign in with Apple was linked on the old one. Sign in with the same Apple account on the new iPhone and everything comes back. Without Apple linked, the anonymous account stayed on the old device.
What does Premium include?
Shared groups you create and manage, the Secret Santa draw, adding people without the app, wishlist claims, size history and check reminders, and size conversion between EU, UK, US and JP. Your own sizes, privacy controls, joining groups and groups on this iPhone are free.
How do I restore a purchase?
Open the paywall and tap Restore purchases.
How do I cancel a subscription?
Subscriptions are managed by Apple. On your iPhone, open Settings > your name > Subscriptions, choose Sizebook and cancel.
Who can see my sizes?
Only the groups you share with, and each group sees only what you choose for it. Entries marked “Only me” are never shared with anyone.
How do I delete my account?
Go to Profile > Delete my account. Your account, sizes and group memberships are removed from our servers.
Is the size conversion exact?
No, it is approximate. Sizing varies between brands, so use it as a guide and save the size that actually fits you for each brand.
