What is OpenWhen?

OpenWhen is a free digital "Open When" letter platform launched February 2026 at openwhen.cards. Users create sealed letters for specific moments ("Open When You Miss Me," "Open When You're Sad," "Open On Our Anniversary"), optionally protected by a guardian question or a date lock, and revealed through an interactive wax-seal ritual. It also offers Note Jars that open one note at a time and Group Jars that many people write into. No account required. Free, with optional one-time upgrades.

Key Features

  • Guardian Questions and Date Locks: Optionally protect a letter with a question only the recipient can answer, a date it unlocks, or both
  • No Account Required: Zero registration. Create, share, done
  • Long Letters: Up to 12,000 characters per letter
  • 20+ Message Templates: Pre-written for long distance, anniversaries, birthdays, bad days, and more
  • Note Jar: A jar of notes that opens one a day, every other day, weekly, or all at once
  • Group Jar: Many people add notes to one shared jar for a farewell, birthday, wedding, or retirement
  • Premium Message: Handwriting fonts, photo, voice memo, any song, reveal effects, premium envelopes (one-time, $1.99 to $3.99 by country)
  • Occasion Add-ons: Birthday candles and an anniversary counter ($1.99 each)
  • Mobile-First: Responsive web app, works on all devices
  • Privacy-First: Letters never expire automatically, encrypted in transit and at rest, no advertising cookies

How It Works

  1. Step 1, Write: Write a letter of up to 12,000 characters, from a template or from scratch. Add a sticker, song, photo, or voice memo.

  3. Step 3, Share: Get a unique link and share it by text, WhatsApp, or social media, or have OpenWhen email it to the recipient.
  4. Step 4, Reveal: The recipient answers the question if there is one, holds a finger on the wax seal to break it, and reads the letter.

Frequently Asked Questions

How do I create an Open When letter?

Visit openwhen.cards/create, write your message (or choose a template), add a guardian question, and share the link. It takes about 2 minutes. No account needed.

Is OpenWhen completely free?

Yes. Sealed letters with text, guardian questions, date locks, the wax seal ritual, free stickers, and curated songs are free and unlimited. Optional upgrades are one-time purchases starting at $0.99. There is no subscription.

Do I need to create an account?

No. OpenWhen requires zero registration. Create a letter and share the link immediately. Premium purchases are linked to your device cookie.

What are the best Open When letter ideas?

The most popular are "Open When You Miss Me," "Open When You're Sad," "Open On Our Anniversary," "Open When You Need a Laugh," and "Open When You Need Courage." OpenWhen has 20+ ready-made templates you can customize.

How secure are my messages?

The sender can protect a letter with a guardian question, so the link alone will not open it, and content is encrypted in transit and at rest. Letters never expire automatically: they are kept until the sender disables them with their manage link, unless the sender sets an expiry date.

Can I send anonymous messages?

Yes. The signature field is optional. You can send a sealed letter without revealing your identity.

How is OpenWhen different from a regular card or text?

OpenWhen adds ritual and protection. Your letter is sealed with a wax stamp, guarded by a question, and revealed through an interactive hold-to-break animation. It transforms a simple message into an experience. And it is free.

Can I use OpenWhen for non-romantic messages?

Yes. OpenWhen works for best friends, parents, siblings, teachers, and your future self. A Group Jar lets a whole team or family write to one person together.

What premium features are available?

Premium Message is a one-time purchase priced by country, from $1.99 to $3.99. It unlocks 4 handwriting fonts (Dancing Script, Great Vibes, Caveat, Pacifico), a photo, a voice memo, any song from iTunes search, reveal effects (polaroid, burn, peel, scratch, typewriter), premium envelopes and themes, and gift card attachments. Premium stickers are $0.99 each or $2.99 for all 25. Birthday candles and an anniversary counter are $1.99 add-ons.

What is a Note Jar?

A digital jar of short notes and letters, like "reasons I love you" or shared memories, that opens one note a day, every other day, weekly, or all at once. Up to 7 notes are free; up to 100 is a one-time $3.99.

What is a Group Jar?

One shared jar that friends, family, or coworkers each add a note to, for a farewell, birthday, wedding, retirement, or new baby. Collecting notes is free and contributors never pay. Sealing more than 7 notes (up to 100) is a one-time $12.99 paid by the organizer.
