How Digital Time Capsules Work
Secure Encryption
Your message is encrypted using industry-standard algorithms before being saved to a file. Without the password, the content remains unreadable. We use AES-256 encryption for maximum security when you choose the strong option.
Future-Proof Format
Capsules are saved as standard HTML files that can be opened by any web browser, now and in the future. The decryption happens in the browser - no special software needed when it's time to open your message.
Self-Contained
Each capsule contains everything needed to decrypt it - no server connection required when opening. This ensures your message remains accessible even if our service is no longer available in the future.
Pro Tip: For important capsules, save multiple copies in different locations (USB drive, cloud storage, printed copy). Consider sharing the password with a trusted person in case you forget it.
Frequently Asked Questions
Is my message stored on your servers?
No. All processing happens in your browser. When you download your time capsule, that's the only copy that exists. We never receive or store your message contents on our servers.
What happens if I forget the password?
Without the password, your message cannot be decrypted. This is why we recommend using a password hint and storing the password securely. We cannot recover lost passwords due to the encryption design.
How long will my time capsule remain usable?
The HTML format ensures your capsule should be openable for decades. For extremely long-term storage (10+ years), consider also saving a plain text version in a sealed envelope as backup.
Can I include images or attachments?
Currently the tool supports text only. For multimedia, consider creating a ZIP file with your time capsule HTML and additional files, encrypting the entire package with the same password.
Is there a limit to how far in the future I can set the open date?
No technical limit exists, but remember you'll need to maintain access to the file and password. For dates beyond 10 years, consider setting calendar reminders and sharing access details with trusted individuals.
