Your files are stored across AWS and Cloudflare infrastructure with 99.999999999% durability - that's independent of our company. Even if SealedFor ceases to operate, your encrypted files remain safely on cloud infrastructure. We are committed to long-term operation and have contingency plans to ensure capsule delivery.
All uploaded files (videos, photos, audio, documents including .txt and .pdf) and written text messages are encrypted with AES-256 at rest. By default, encryption keys are managed on our servers — theoretically only the CEO, who holds the master encryption key, could decrypt content. For stronger protection, enable the Privacy Shield add-on: it encrypts your data with a unique viewing key shown only once and not stored on our servers after creation. Note: during the encryption process the key briefly passes through our server. Without the viewing key, nobody can decrypt your files and messages afterward.
We send you a check-in email at an interval you choose (every 1, 3, 6, or 12 months). You simply click a link to confirm you're okay. If you stop responding after multiple attempts and a grace period, your capsule is automatically delivered to your recipients.
No account is needed. After payment, you receive an edit token via email. This token lets you manage, update, or deliver your capsule early at any time. Bookmark it or save the email - it's your key.
Videos, audio, photos, and documents — we support all popular formats including MP4, MP3, JPG, PNG, PDF, DOCX, and many more. Plus a text message up to 15,000 characters.
Yes. You pay once and your capsule is sealed for up to 150 years. No monthly fees, no hidden charges, no subscriptions. Your base plan includes 15 years of storage, and you can extend in 5-year increments at a small fee.
You can update the text message, delivery settings, recipients, and file titles at any time using your edit token. However, new files cannot be added after the capsule is sealed. Make sure to upload everything you need during creation.
Create your first capsule in under 5 minutes. No account needed.
