Write a letter to your future self. Choose when it arrives — tomorrow, next month, or years from now. Then forget you wrote it. When the day comes, Unseal delivers your letter back. A message from past you, arriving exactly when you need it. Between your own letters, read anonymous letters from strangers around the world. Real people, real emotions, no profiles, no usernames — just honest words. WRITE & SEAL Pour your thoughts into a letter. Pick a delivery date. Seal it shut. PEN PALS Exchange anonymous letters with someone in another city. No profiles. No DMs. Just letters. BOTTLE MESSAGES Write a letter and throw it into the ocean. A stranger finds it days later. Reply if it moves you. COMMUNITY DROPS Time-limited letter events around themes like gratitude, mental health, or seasons of change. LETTER CHAINS Read the letter before yours. Then write the next one. Watch a chain of anonymous letters grow. SEALED TIL COLLECTIONS Group time capsules. "Sealed til graduation." "Sealed til I turn 30." Everyone opens together. Your letters are private and encrypted. Shared letters are fully anonymous — no usernames, no profiles, no way to trace them back to you. Every community letter is reviewed before it appears. UNSEAL PRO Free to use. Unseal Pro ($5.99/month or $29.99/year) unlocks unlimited pen pals, priority delivery, photo attachments, anniversary letters, mood journey, PDF export, and more. Payment is charged to your Apple ID account. Subscription automatically renews unless cancelled at least 24 hours before the end of the current period. Manage subscriptions in your Apple ID account settings. Privacy Policy: https://public-site-taupe.vercel.app/privacy Terms of Use: https://public-site-taupe.vercel.app/terms
