Privacy & Encryption
Your words. Yours alone. Until the moment they're meant to be read.
WordsLater is built so that the most private words you'll ever write - letters to your children, final messages, deeply personal memories - stay private. Encrypted on your device, encrypted on our servers, encrypted in transit, and only ever readable by the people you choose, at the time you choose. Here's how.
Privacy Built Into Every Layer
Six pillars that protect your messages from the moment you write them.
AES-256 Encryption at Rest
Every message, attachment, photo, and recording is encrypted with AES-256 before it's written to storage. The same standard trusted by banks and governments worldwide.
TLS 1.3 in Transit
Everything moving between your device and our servers - and from our servers to your recipients - is wrapped in modern TLS encryption with forward secrecy.
Per-Message Keys
Each message gets its own encryption key. A compromise of one message can never cascade to expose others. Keys are managed by a hardware-backed key service.
Zero-Knowledge Posthumous Vault
Messages marked for posthumous delivery are sealed in a vault that no WordsLater employee can open. Only the verified release process can decrypt them, only at the time of delivery.
Strict Access Controls
Internal access to any production system requires SSO, hardware MFA, and a documented business reason. Every access event is logged and reviewed.
Minimal Data Collection
We collect only what we need to deliver your messages reliably - and nothing we'd rather not have if a breach ever happened. No ad tracking, no data brokering, ever.
The Journey of a Message
Follow your message from the moment you write it to the moment it arrives.
You write
As you compose, drafts are saved over an encrypted TLS connection to your account.
We encrypt
When you save, your message is encrypted with a unique AES-256 key. The key is wrapped by our hardware-backed key service and stored separately from the data.
We store - safely
Encrypted content lives in geographically redundant storage. Without the matching key, the data is unreadable - even by us.
We wait
Your message sits sealed until its trigger fires - a date, a milestone, or a verified posthumous release. While waiting, no one can read it.
We deliver
When the trigger fires, the message is decrypted and delivered to your chosen recipients over TLS. Delivery is logged; the plaintext is never stored.
We clean up
After successful delivery and any retention window you've chosen, the encrypted record is securely destroyed in accordance with our Data Retention policy.
Privacy you can hand down for a lifetime.

Frequently Asked Questions
Can WordsLater employees read my messages?
For posthumous-vault messages: no - they're sealed in a way that no employee can decrypt. For all other messages, access is technically possible only with strict, audited internal controls, and is forbidden by policy except for narrow troubleshooting situations with your consent.
What happens if my account is hacked?
We protect against this with strong password requirements, optional two-factor authentication, anomalous-login detection, and a forced 7-day cooling-off window before any sensitive change (recipient swaps, posthumous release dates, trusted-contact changes) takes effect.
Do you use my messages to train AI?
Never. Your content is not used to train any AI model, ours or anyone else's. We don't share it with third parties for analytics, marketing, or model training under any circumstances.
Where is my data stored?
In geographically redundant, audited data centers in the United States by default, with options for EU residency on enterprise plans. See our Data Retention & Custody page for details.
Can I delete everything if I change my mind?
Yes - permanently. Account deletion securely removes all encrypted content, metadata, and backups after a short cooling-off period (so a malicious actor with momentary access can't wipe a lifetime of work).
What if I lose my password?
You can reset your password using your registered email or phone. For accounts with high-value posthumous content, we recommend turning on two-factor authentication and confirming your recovery contact information during periodic check-ins.
Is WordsLater GDPR and CCPA compliant?
Yes. We honor data access, portability, correction, and deletion requests under both GDPR and CCPA. See our Privacy Policy for the full details on how to exercise your rights.
Are attachments and recordings encrypted the same way?
Yes. Photos, documents, voice notes, and videos are encrypted at rest with per-message keys derived from your account, and re-encrypted in transit on every delivery.
