Our Pledge
For paid capsules — Personal+, Family, Legacy, the one-time Gift Capsule, or the per-capsule "Keep forever" purchase — we commit to maintaining access for at least 30 years from the date you seal it. After that, for as long as there are people on Earth with an internet connection and someone who cares to read what you wrote, we'll keep the lights on.
For free capsules, the policy is honest about its limits: by default they're kept for 30 days after they open (you can opt in at creation to keep them for up to 1 year). After that they're deleted unless you make them permanent for €5 — and we send a warning email two weeks before deletion with a one-click "keep forever" link. This split lets the free tier exist without the storage commitment becoming dishonest.
Time Capsule is built around a simple faith: that what you seal today will be readable by whoever you meant to reach it — in ten years, in twenty-five, in more. That promise is easy to make and easy to break. We want to make it harder to break.
This page explains exactly what we're committing to, how we're structured to keep that commitment, and what you can do if we ever fail.
These are constraints we've placed on ourselves — not aspirations, not preferences. Constraints.
Single points of failure are the enemy of 30-year commitments. The founder gets sick. A company goes under. A country changes its laws. Any of these can end a service overnight.
So the service runs with a minimum of five named custodians — people spread across countries and generations, each with full access to the infrastructure, the codebase, and the ability to keep things running independently if everything else fails.
At least one custodian must be under 30 years old. At least two must be in different countries. All five must confirm annually — publicly, on this page — that the service is funded and operational.

A percentage of every Legacy plan payment goes directly into a dedicated sustaining fund — separate from operating revenue, not accessible for day-to-day costs. This fund exists for one purpose: to keep the service running if it stops growing.
This is the same model that Posthaven uses. The idea is simple: if the service ever stops generating enough revenue to sustain itself, the fund covers it — for as long as the fund holds. Legacy users are not just paying for features. They are contributing to the structural resilience of the archive.
This is the one promise that doesn't depend on the service staying online.
If this service shuts down for any reason, every user will receive a full export of their content: plaintext messages, attached files, metadata, and the capsule structure — in an open, documented format that does not require us to exist to read it. This export will be delivered before any shutdown date.
Your memories belong to you. The service is the vehicle, not the vault.
Honesty matters more than reassurance here.
This page is the public record. If we ever act against anything written here, you can point to it. The custodians are named here. The terms are written here. This is not a legal contract — but it is a public promise, made by people who've put their names to it, and that is worth something.
If you believe we are in breach of this pledge, you can contact any named custodian directly. Their contact information is linked from their name once confirmed.
The full codebase for this service is available for audit. The data format is documented. We have designed the system so that it could be run independently of us.
This pledge was written in 2026 and will be updated publicly whenever any of its terms change. Prior versions will remain linked here.
