Managing Your Account & FAQs
All your questions about subscriptions, payments, and billing cycles answered here.
Can anyone read my messages?
No. Messages are encrypted on your device and can only be decrypted by the intended recipients. Not even Sealed can read them.
What data is stored on the blockchain?
Only encrypted message envelopes, payment records, and protocol parameters. Message content and user identities are never public.
Does Sealed know who I am talking to?
No. Sealed does not have access to your contact graph. Each message is delivered to a unique, non-linkable destination.
Why does sending a message cost money?
Messaging on Sealed is paid because each message is a real transaction on the blockchain, so it comes with a gas fee. A transparent application fee also prevents spam, removes ads and data monetization, and allows Sealed to operate without central servers.
How much does a message cost?
The cost depends on your selected tariff or subscription and is calculated per 2 KB of encrypted data. The exact price is always shown before sending.
