> One capsule for your wedding, shower or birthday. Guests scan a QR and write a letter with no account. Each letter is sealed until the date you choose.

Sealtrove keeps one capsule of guest letters per event: a wedding, a baby shower, a birthday or another occasion. The host signs in with a passkey (WebAuthn; no password, no email address), names the capsule, gives the event date and chooses an open date: the 1st, 5th or 10th anniversary, 18 years on for a shower, or a custom date, at most 10 years after the event (21 for a shower). Guests scan a QR code or open a link and write a letter of up to 3000 characters with no account, until 23:59 on the last day for letters (7 days after the event by default, at most 90) in the capsule's time zone. Every letter is sealed on the server the moment it is sent: before 09:00 on the open date the server shows a count and nothing else, to anyone, the host included, in every page and download. On the open date the capsule becomes a keepsake page to read, print and download (JSON, and CSV for upgraded capsules). Printables are made in the browser: an A5 QR sign, table cards 4 to a page, and an envelope pack with one letter a page folding into a DL envelope. Capsules and letters are kept in a Cloudflare D1 database until the host deletes them; the guest link secret, session ids and the recovery code are stored only as SHA-256 digests.

- [Terms of use](https://sealtrove.com/terms/): What the site can be relied on for, the letters, acceptable use and support.

## Pricing

Free. No paid plan is offered at present. Each capsule holds 50 letters, 2 capsules may wait to open at one time, and every printable and download is on.

## What it is not

- Not affiliated: Sealtrove is not affiliated with any venue, planner, stationery brand or time-capsule service.
- Not locked with a key the host holds: sealed means the server will not show a letter before the date.
- Not a promise beyond what a website can keep: hosts should download the letters once they open.
- Not a chat or guest book: guests cannot read letters, their own included, and are never emailed.

## Optional

- [Full text of every page](https://sealtrove.com/llms-full.txt): every page as Markdown, in one file.
