Why SaidMe?

SaidMe (留了么) is a secure, privacy-focused "dead man's switch" service. It ensures that your most critical messages are delivered to your trusted contacts if you are unable to do so yourself.

How It Works

1. Write: Compose your message. It is encrypted on your device using keys that only you control initially.
2. Assign: Designate up to 2 trusted recipients (email).
3. Check In: Use the iOS app to check in periodically (e.g., every 30 days).
4. Deliver: If you miss a check-in deadline (plus any grace period), the server automatically decrypts and delivers your message to your recipients via email.

Key Features

🔒 End-to-End Encryption

We use industry-standard Envelope Encryption (AES-256-GCM + RSA-OAEP). Your message content remains encrypted at rest. We cannot read it until the trigger condition is explicitly met.

⚡️ Flexible Intervals

Choose a check-in frequency that suits your lifestyle.

• Free Tier: 30-day fixed interval.
• Lifetime Access: Customize your interval from 1 day to 30 days.

⏳ Grace Period

Prevent false alarms with our new Grace Period feature (exclusive to Lifetime Access). Set a buffer of 1 to 48 hours after your deadline. If you forget to check in, you have this extra time to reset the timer before any messages are sent.

👥 Backup Recipients

Add a second trusted recipient to ensure redundancy. If your primary contact misses the email, your backup will receive it.

🔄 Smart Resend Logic

For maximum reliability, Lifetime Access users benefit from our Smart Resend system. If a trigger event occurs, we will attempt to deliver the message 3 times (once every 24 hours) to ensure it is not missed.

We believe in simple, transparent pricing. No subscriptions.
