Frequently Asked Questions#
1. What is Sealed Letter?#
Sealed Letter is a quiet, private space for words that matter. Our app helps you capture, store, and share important notes or messages with complete control over your data.
2. Where is my data stored?#
Currently, your data is stored securely in the AWS Oregon region (USA). In the future, we will provide options for other regions so you can choose where your data lives.
3. Do you use cookies or trackers?#
No. We do not use cookies, tracking pixels, or third-party analytics tools. Your privacy is our highest priority.
4. How secure is the service?#
We use industry-standard encryption, secure authentication, and AWS best practices to protect your information. Our team also holds security certifications and follows strict codes of ethics.
5. Can I access my account on multiple devices?#
Yes. You can log in to your account on any supported device, and your notes will stay synced across them.
6. What happens if I forget my login password?#
You can reset your password at any time by requesting a reset link to your registered email. For security, the link will expire after a short time.
7. What happens if I forget my letter password?#
If you forget the password for a letter, unfortunately the letter is permanently inaccessible. For security and privacy reasons, we never store or keep a copy of your passwords. This ensures that only you, and the people you choose to share it with, can access your content.
Please make sure to save your letter passwords in a secure place. Once lost, there is no way for us to recover or reset it.
8. Do you offer subscriptions?#
Yes. Subscriptions and in-app purchases are managed securely through RevenueCat, integrated with the Apple App Store and Google Play Store.
9. Can I delete my account and data?#
Absolutely. You are in full control of your data. You can request deletion from within the app, and we will permanently erase your account and stored information.
10. Is Sealed Letter available in multiple languages?#
Yes. The app and this website support several languages, and we continue to expand our language options.
11. How can I get support?#
You can reach our support team directly through the app. We aim to respond quickly and personally to all requests.
12. What is a Trusted Contact?#
A Trusted Contact is someone you designate to confirm your letters should be released.
13. What does a Trusted Contact need to do?#
Their only responsibility is to notify us that your letters should be released. Once confirmed, your letters will be shared with the method and people you’ve chosen.
14. Can a Trusted Contact read my letters?#
No. They cannot access any aspect of your letters or change their contents. They only confirm the release of your letters.
15. How do I choose a Trusted Contact?#
Pick someone you trust deeply, such as a close friend or family member, who will be able to act responsibly on your behalf.
16. Can I have multiple Trusted Contacts?#
Yes. You can assign multiple Trusted Contacts to provide flexibility and peace of mind.
17. What is a Release Contact?#
A Release Contact is the counterpart of a Trusted Contact. If you are a Release Contact, it means that person has trusted you to confirm when their letters should be released to the recipients they have chosen.
18. What is a Letter Author?#
A Letter Author is the person who writes and stores letters in the app.
19. What can a Letter Author do?#
They can write, update, and manage their letters, and choose recipients who will receive them.
20. How are a Letter Author’s letters protected?#
Letters are securely encrypted. Only the chosen recipients will receive them once the Trusted Contact confirms their release.
21. Can a Letter Author change their Trusted Contacts?#
Yes. A Letter Author can update or replace their Trusted Contacts at any time.
22. Do I need a subscription to receive letters?#
No. Letters that are prepared for pickup can be accessed on the website using the provided letter details or QR code, without an account or subscription. Letters sent for in-app delivery also do not require the recipient to have a subscription.
23. Do I need a subscription to be a Trusted Contact?#
No. Any registered Sealed Letter user can be designated as a Trusted Contact. A subscription is not required for this role.
24. Why do letters have a minimum cooldown period of 31 days?#
The minimum cooldown period is intentional and helps maintain the purpose of Sealed Letter. It ensures the service is used for purposeful message delivery, rather than ongoing or real-time communication, and helps prevent it from becoming a general messaging platform.
25. What does pick-up delivery mean?#
Pick-up delivery means a message is made available for access outside of the app. The recipient can retrieve the message using the provided letter details or QR code, without needing a Sealed Letter account or subscription. This option is designed for situations where simple, anonymous and direct access is preferred.
26. What does in-app delivery mean?#
In-app delivery means the message is delivered directly to a specific Sealed Letter user and can be accessed securely within the app. The recipient does not need a subscription to receive the message, only an account. This option is more convenient, as the recipient does not need to manage separate passwords or letter access codes.
27. Which delivery option is more secure?#
Letters sealed with an author-defined password offer the highest level of isolation. The password is never stored by Sealed Letter and must be shared by the author with the intended recipient. Without it, the letter cannot be decrypted or accessed.
In-app delivery prioritizes convenience. To deliver the message to a specific user account, the system must temporarily decrypt and process the message as part of the delivery flow. This is done securely, but it means the system is involved in the delivery process.
Both options are secure by design. The difference lies in the trade-off between maximum isolation (password-sealed pickup letters) and ease of access (in-app delivery), allowing senders to choose what best fits their needs.
28. Can Sealed Letter staff read my letters?#
No. Letters prepared for pick-up are sealed with a password that is never stored by Sealed Letter. Without that password, the letter cannot be decrypted.
Letters sent via in-app delivery are protected using industry-standard encryption aligned with AWS best practices. Access to the encryption keys is strictly limited to the systems required to securely process delivery to the intended recipient only. Also see FAQ 27
29. What happens to my letters if I delete my account?#
When you delete your account, all associated account information, letters, and related metadata are permanently removed from the active system.
As part of our disaster recovery strategy, encrypted backups are retained for a limited time in dedicated AWS accounts. Any remaining data in these backups is automatically rotated out and permanently deleted within 12 months.
30. What happens if Sealed Letter shuts down?#
We are committed to long-term availability. In the unlikely event of major service changes, we would provide clear advance notice and practical guidance so users can access or export their content in a timely manner.
31. Why should I trust you?#
Sealed Letter started with a simple, personal question shared by friends and family: what happens to our digital lives if something happens to us? This is a service we use ourselves, and one we built to solve a real problem. From the beginning, we’ve focused on care, security, and respect for privacy.
The integrity the project started with is the integrity we intend to maintain.
32. Why does the app look a bit plain?#
We’re at the very start of this journey, and we’ve had to make some intentional choices about where to focus first.
Our energy has gone into building a reliable, secure foundation — the parts you don’t see, but that matter most. Design and polish are important to us too, and we’re actively working toward making the app look as good as it feels to use.
Thanks for bearing with us while we get there 😊
33. My contact never received my invite#
If you invited someone to Sealed Letter who wasn’t a member at the time, they won’t receive the invite after signing up. Please delete the pending invite from your contacts and send a new invitation.
