Privacy Policy

1. Who we are

Letter4U is a service for creating and sharing digital letters, memory pages, interactive templates, and related media. Questions or privacy requests may be sent to kenjibuena.business@gmail.com.

2. Information we collect

We collect the account information you provide through Google Sign-In, such as your account identifier, email address, and display name. We also process page content you submit, including text, photos, audio, video links, template settings, custom page names, drafts stored on your device, support messages, and abuse reports.

When you use Letter4U, we may process basic technical information such as browser or app type, approximate network information, security and rate-limit identifiers, timestamps, crash details, and interaction records needed to operate and protect the service. Raw IP addresses are not stored in page abuse reports; a one-way hash is used for abuse prevention.

3. Purchases and credits

On Android, digital-credit purchases are processed by Google Play Billing. Google may provide Letter4U with purchase tokens, product identifiers, transaction status, and account-matching identifiers so we can verify and deliver credits. Letter4U does not receive your full card number. Web payments may be processed by PayMongo, which handles payment details under its own privacy terms.

4. How we use information

We use information to authenticate you, save and publish pages, deliver purchased or earned credits, provide previews, prevent fraud and abuse, respond to support requests, moderate reported content, maintain service reliability, and comply with legal obligations.

5. Public and shared content

Published pages are available to anyone who has or discovers the page link. A recipient may copy, capture, or re-share content. Do not publish confidential information unless you are comfortable sharing it with the intended audience and anyone who may receive the link.

6. Service providers

We use service providers including Google Firebase for authentication, databases, storage, and cloud functions; Google Play for Android billing; Vercel for web hosting and delivery; PayMongo for supported web payments; and YouTube when a template embeds a YouTube video. These providers process information under their own terms and privacy policies.

7. Retention and security

We retain account and page information while your account is active or as needed to provide the service. Security logs, transaction evidence, and fraud-prevention records may be kept for a limited period after deletion where required for legal, accounting, dispute, or security purposes. We use access controls, server-side authorization, validation, rate limits, and restricted Firebase rules, but no online service can guarantee absolute security.

8. Your choices and rights

You may update your profile, delete individual pages, or request full account deletion. The public deletion instructions are available at letter4u.me/account-deletion. Depending on your location, you may also have rights to access, correct, object to, restrict, or obtain a copy of personal information.

9. Children

Letter4U is not directed to children under 13. If local law requires a higher minimum age or parental consent, that rule applies. Contact us if you believe a child has provided personal information without required consent.

10. Changes

We may update this policy as Letter4U changes. The effective date above identifies the current version. Material changes may also be communicated in the app or website.
