Letters — Privacy Policy
Last updated:
The short version
Letters has no advertising. We do not sell your personal information or share it for advertising or cross-app tracking. We use information to run your account, deliver the features you choose, protect the community, resolve problems, and meet legal obligations. The developer identified on the Letters App Store listing is responsible for this use of your information.
Information Letters handles
Account and profile information includes your email, username, date of birth, avatar, biography, location, and family details you provide, such as the number and ages of your children or stage of parenthood. Selecting a location can store the place name and its coordinates. We also store the posts, comments, messages, shared media, product reviews, saved items, likes, blocks, and account activity needed for those features. Subscription records include product identifiers and entitlement information, not your full card details. Notification tokens and technical information, such as device/app versions, network metadata, errors, and performance events, support delivery, security, and diagnostics.
Why we use it
We use this information to sign you in, display your profile and content, deliver conversations, look up products, check subscription access, send requested notifications, investigate abuse, and fix faults. Product lookups send the barcode and relevant product/search information to product-data services. Ingredient and additive lookups send product ingredient information to our backend. Where data-protection law requires a legal basis, we rely on providing the service you request, legitimate interests in security and reliability where permitted, legal obligations, and consent where required. We do not use private messages or family details to target advertising.
What other people can see
Your profile and community posts, comments, and reviews are visible to other users as part of the app’s features. Posts shared through public links may also be visible outside the app. Share only what you intend others to see. Private messages are delivered to the participants in that conversation and stored by our service; they are not end-to-end encrypted. Operational access may be needed to deliver the service, investigate abuse, provide support, or comply with law. Recipients can save or screenshot information. Avoid sharing sensitive information or unnecessary identifying details about children.
Services that help Letters work
Supabase provides account authentication, database, file storage, and backend services. Apple provides App Store purchases, notification delivery, and Maps location search. If you choose Google sign-in, Google handles that sign-in and supplies account information needed to authenticate you. Open Food Facts supplies product information and receives product lookup requests, including ordinary network metadata such as your IP address. When configured, Sentry receives error and performance diagnostics. These services have their own privacy information. Providers may process information outside your country; contact us for details about hosting locations and safeguards. We may also disclose information when legally required or needed to address fraud, abuse, or safety threats.
Camera, photos, location, and notifications
The scanner uses camera frames on your device to detect barcodes. Its barcode lookup does not upload the camera video. Photos or media you deliberately attach to a profile, post, or message are uploaded so they can be displayed or delivered. Location selection uses Maps search; the app does not continuously track your movements. Notifications are optional and can be changed in iOS Settings. You can also change camera and photo permissions there; turning them off may prevent the related feature from working.
Keeping and deleting information
We keep information for as long as needed to provide your account and the features you use, resolve problems, protect the service, or meet legal requirements. You can request permanent deletion in Account Settings → Delete account. Requests are processed in the background, rather than deleting every record instantly. Limited records may remain where required for legal or security reasons, and backup copies may remain until overwritten. Other people may retain copies they saved. Apple manages its own purchase records. Contact us for details about retention for a particular type of information.
Protecting your information
We use encrypted network connections and service access controls to protect information. No online service can guarantee absolute security. Keep your account access secure, and contact us if you suspect unauthorised access or a privacy problem.
Your choices and rights
You can edit available profile fields, change device permissions, block users, and request account deletion. Depending on where you live and the applicable legal basis, you may also have rights to access, correct, obtain a copy of, delete, restrict, or object to the use of your personal information, and withdraw consent where processing relies on it. Contact us to make a request; we may need to verify your identity. You can also complain to your local data-protection authority. Nothing in this policy limits rights granted by law.
Children’s information
Letters is intended for adults, not for children to create their own accounts. Parents and caregivers may provide limited family information, such as children’s ages, for their own profile. Avoid sharing children’s full names, addresses, schools, sensitive health details, or photos you do not have permission to share. Contact us if you believe a child has created an account or information about a child should be removed.
Contact and policy updates
For privacy questions, information requests, or concerns, contact the Letters developer through the App Support contact on the Letters App Store listing. We may update this policy as the app or its services change. We will update the date and explain significant changes through the app or an appropriate account contact channel.
