什麼是 iTellu？

iTellu lets you write a message today and open it exactly when you choose — a prediction, a letter, a promise. Every iTellu is sealed with end-to-end encryption and a certified RFC 3161 timestamp, so no one can claim you wrote it later. Share a clean link, get a verifiable certificate. No app to download. Free to start
