A digital time capsule is a set of files and messages you seal today and that can only be opened on a future date you choose. Time Capsule is a digital time capsule service: you add photos, videos, documents and a written message, pick the opening date and the recipients, and the capsule stays locked until that day arrives. ### How does a digital time capsule work? You create a capsule, add your files and your message, choose one or more recipients and an opening date, then lock it. From that moment it cannot be edited or opened early. Your recipients are emailed that a capsule is waiting for them, and again on the opening date, when they can read it and download everything. ### Can I send the capsule to multiple people? Yes, simply add the emails of all the people or send them the link or QR code of the capsule. ### Can I modify a capsule that is already locked? No, like a time capsule buried underground, it is impossible to modify it once locked. ### Can I delete a capsule? Yes, a capsule can be deleted by its creator at any time. ### Can I change the opening date of a capsule? No, the opening date cannot be changed after it has been scheduled. ### What is Time Capsule? Time Capsule (time-capsule.io) is a digital time capsule service. You create a capsule containing photos, videos, documents and a written message, and send it to whoever you want — friends, family, or yourself — with a specific opening date. It is run by three brothers through Reen Tech LLC, a registered company in California. ### What is the purpose of a Time Capsule? It allows you to send a piece of the present into the future, to a date decided when locking the capsule. ### What type of content can I put in a capsule? Photos Videos Messages Documents Audio ... ### Who can access my capsule? Only people with the link will be able to access it. You can also add a password for extra security. Capsules are not end-to-end encrypted, though — see "How is my data protected?" for exactly who could technically reach stored content. ### What happens if Time Capsule shuts down? We'd never just disappear with your capsules. If we ever had to wind the service down, we commit to two things: we'll warn you well in advance, and we'll release every pending capsule early — delivering your messages ahead of their date rather than letting them be lost. You'd get your memories back, not a dead link. The honest reason we'd ever stop: the only thing that could force it is the running cost (the company and the servers). We keep that cost deliberately low, and we'd seek help from our community to keep it alive before ever going dark. ### Will my data still be here in 10, 20, or 30 years? Your capsule is stored, sealed, until its opening date — our plans cover up to 30 years, and you can schedule beyond that for a small per-year add-on. We've built on durable, professional infrastructure (Cloudflare R2 and D1, encrypted at rest) and we take preservation seriously. But we won't insult you with unbackable permanence claims — no one can honestly promise that. What we can promise: on opening day you download everything in standard formats and keep your own copy, and if we ever wind down we'll release your capsule early. The most durable copy is the one in your hands, and we make sure you get it. ### Who is behind Time Capsule? Three brothers — a CTO, a software engineer, and a math teacher. Two of us became fathers and wanted to send messages their daughters would open years later; the idea pulled all three of us in. Time Capsule is operated by Reen Tech LLC, a registered company in California. We run it carefully and personally — it's not a faceless platform. The full story is on our Preservation page.
