Our Pledge

Your memories will still be here.

For paid capsules — Personal+, Family, Legacy, the one-time Gift Capsule, or the per-capsule €5 “Keep it here” 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: they remain available for 30 days after opening. After that they are deleted unless you pay €5 to remove scheduled deletion — and we send a warning email two weeks beforehand with a direct payment link. You can also download your own copy. 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.


What we won't do

These are constraints we've placed on ourselves — not aspirations, not preferences. Constraints.


The stewardship model

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.

The continuity model we are working toward would use five named custodians — people spread across countries and generations who could help keep the service accountable and operational if its founder cannot.

The intended group includes at least one custodian under 30 and people in more than one country. Until those people are confirmed publicly on this page, responsibility remains with the founder alone.

The proposed sustaining fund

A dedicated sustaining fund does not exist yet. Until it is formally created, ring-fenced and reported on this page, Legacy payments are ordinary operating revenue and we will not describe any portion of them as protected reserves.

Our intended model is to place a published percentage of future Legacy revenue into a separate reserve used only for continuity costs. If that structure is established, this page will state the percentage, legal owner, balance-reporting method and withdrawal rules. Until then, it is a plan, not a feature customers are buying.


Data portability — the hard guarantee

This is the one promise that doesn't depend on the service staying online.

You can download content after it becomes readable. For capsules that are still locked, we can provide the encrypted package and its metadata, but we cannot truthfully promise plaintext before the cryptographic unlock date. The time lock is specifically designed so that we cannot decrypt it early. Any shutdown export must preserve that distinction.

Your memories belong to you. We are working toward a documented export format that lets unlocked content travel independently of this interface; until that export is implemented and tested, we will not market it as a completed guarantee.


What we're not promising

Honesty matters more than reassurance here.


How to hold us to this

This page is the public record. It shows which continuity measures exist today and which are still proposed. At present, João Tomé is the only named responsible person; future custodians will be added only after they accept the role publicly. This is not a legal contract, and it must not imply safeguards that have not been built.

This pledge was written in 2026 and will be updated publicly whenever any of its terms change. Prior versions will remain linked here.
