Canister Guide
An anniversary message that unlocks on the day you choose
Write to your partner today about what you hope your relationship looks like next year — or next decade — and open it together when the date arrives.
Celebrate forward-looking love
Anniversary messages often look backward. A forward-looking capsule asks: what do I want us to remember about this season of our life? Seal that reflection now; open it on a future anniversary.
Pair with photos and mementos
Add scans of tickets, trip photos, or a voice memo on Signature ($12 one-time) or Legacy ($39 one-time). Content is encrypted client-side before upload.
A ritual you can repeat
Many couples create a new capsule each year — a growing chain of sealed moments. Each capsule is priced once with no subscription.
Common questions
Is an anniversary capsule only for married couples?
No. Any partners celebrating relationship milestones can use Canister the same way.
Can we set reminders before the unlock?
Yes. Configure reminder emails to yourselves or each other (with permission).
How is this different from scheduling an email?
Scheduled email depends on a single provider account staying active. Canister stores encrypted content on decentralized infrastructure with on-chain unlock records.
