Frequently Asked Questions
Can you read my messages?
No. Your messages are encrypted in your browser before they reach our servers. We use AES-256-GCM encryption. Even with full database access, we cannot read your messages.
What if the platform shuts down?
The platform is designed to be self-hostable. The codebase uses standard open-source technologies (Next.js, Supabase) that anyone can deploy. Your encrypted data remains safe regardless.
What if I accidentally trigger the delivery?
The system has multiple safety layers: two warning emails, recipient verification, and a final grace period where you can cancel. The entire process takes at minimum several months with default settings.
Can my recipient open the message early?
No. Messages can only be opened after the delivery process completes. Even then, the recipient needs both the passphrase (which you give them) and access to their email.
What if I lose my edit code?
Unfortunately, there is no way to recover it. This is by design — it ensures that only you can modify or delete your message. We recommend saving it in a secure password manager.
Is this really free?
Yes. The platform runs on free tiers of established services (Vercel, Supabase, Resend). We accept voluntary donations to cover any costs that exceed free limits.
Can someone send harmful messages?
We cannot moderate encrypted content. However, recipients must explicitly consent before any message is armed for delivery. They can decline at any time. Our Terms of Service prohibit threatening or illegal content.
What data do you store?
We store: your encrypted message (unreadable), recipient email addresses (server-side encrypted), your sender email (server-side encrypted for safety checks), and metadata like delivery status and timer settings.
How does the death detection work?
It uses a multi-layered approach: platform inactivity monitoring, optional social media activity checks (YouTube, GitHub), email confirmations, recipient verification, and a final sender alert. All timing is configurable.
Can I leave messages for multiple people?
Yes. You can choose single delivery (one person) or multiple delivery (all recipients receive the message at the same time).
What should I NOT include in my message?
Avoid defamatory or false statements about living persons, information protected by non-disclosure agreements (NDAs), attorney-client privileged information, threats or harassment, and instructions for illegal activities. While we cannot read your encrypted content, you bear full legal responsibility for what you write. Your estate may also be held liable after your passing.
Is my message legally binding?
No. Words Left messages are personal communications, not legal documents. They cannot replace a will, trust, power of attorney, or any other legal instrument. If you need to make legally binding arrangements, consult a qualified attorney.
Can a posthumous message be used in court?
We cannot provide legal advice. Our platform is a private, encrypted communication service. Message content is end-to-end encrypted and inaccessible to us. For questions about the legal admissibility of any communication, please consult a qualified legal professional in your jurisdiction.
What if my message contains sensitive information?
All message content is encrypted with AES-256-GCM in your browser before it ever reaches our servers. Only someone with the passphrase can decrypt it. However, we recommend exercising good judgment about what you include. Once delivered, the recipient controls the decrypted content.
Why does posthumous messaging matter?
Research consistently shows that unexpressed feelings are among the most common regrets of the dying. Modern grief psychology recognizes that maintaining a connection with someone who has passed is a natural and healthy part of healing. Many bereaved individuals report unresolved issues with the deceased that complicate their grief. A final message can provide closure, express love, and bridge the gap that death creates.
