Puffins

Privacy policy

Effective date: 13 September 2026

Puffins is a shared pantry, shopping list, and recipe app for households, developed by Smallbox (“we”, “us”). This policy explains what information the app collects, why, who can see it, and how to remove it. It applies to the Puffins app for iPhone and Android and to the account you create in it.

The short version: we collect only what the app needs to work, we never sell or advertise with your data, and you can delete your account and everything in it from the Profile screen at any time.

We do not collect your location, contacts, calendar, advertising identifier, or any analytics about how you use the app. There are no ads and no third-party trackers.

How we use it

We use your information only to run the app: keeping your account, syncing your household’s pantry, shopping list, and recipes between members, reading receipts and recipes from photos, and sending the emails needed to confirm your address or reset your password. We do not use it for marketing, we do not sell it, and we do not share it with anyone except the service providers listed below.

Reading photos with AI

When you scan a receipt or a recipe, the photo is sent from our server to Anthropic, whose Claude model reads it and returns the items or the recipe as text. Anthropic processes these photos on our behalf as a service provider. Under its commercial terms it does not use them to train its models, and it retains them only briefly for abuse monitoring. The result is shown to you for review before anything is saved.

Claude is AI and can make mistakes. Please double check the items and amounts it reads.

Your household can see what you add

Puffins is built for sharing. Everyone in your household sees the same pantry, shopping list, recipes, and scanned receipts, including who added an item. Anyone who has your household’s invite code can join it, so share the code only with people you want in your household.

Service providers

Your data is stored and processed by these companies, each of which acts on our instructions:

  • Supabase hosts our database, file storage, and sign-in service, and runs the server functions that process photos.
  • Anthropic provides the Claude model that reads receipt and recipe photos.
  • Resend delivers the account confirmation and password reset emails.
  • Apple and Google distribute the app through their app stores and handle any purchase or install data under their own policies.

We do not share your information with anyone else unless the law requires it.

How long we keep it

  • Your account, household content, and receipt photos are kept for as long as your account and household exist.
  • Recipe photos are deleted from our storage immediately after they have been read.
  • Confirmation and reset codes expire shortly after they are sent.
  • When you delete your account, your login, profile, and memberships are removed straight away. A household you own is deleted together with its pantry, shopping list, recipes, and receipts.

Deleting your account

Open Profile in the app and choose Delete account. This cannot be undone. Only you can delete your account.

Security

All traffic between the app and our servers is encrypted in transit. Every record is protected by database rules that allow access only to members of the household it belongs to, and photo storage is private with the same rule. The credentials used to call Anthropic live only on our server and are never included in the app.

Changes to this policy

If we change this policy in a way that matters, we will update the date at the top and email you at the address on your account when the change takes effect.
