One subscription per person. It covers all of your devices, not one of them.
What syncs
- Importance scores and classifications
- Your classification prompts, general and per sender
- Translations you have already paid for
What never syncs
- Your emails — they stay in the local database on each device
- Your accounts and passwords
- Your contacts
- Anything we could read: we hold ciphertext only
How it works
- 1Turn it on and Saymail derives the encryption key on your device. We never see it.
- 2Pair your other devices by scanning a QR code, or by typing a 24-word recovery phrase.
- 3From then on each device uploads what it learned and applies what the others learned.
What is in the price
- Sync between every device you pair
- Bring-your-own-AI included — no separate unlock needed
- 500 credits every month, on yearly billing too
If you cancel, or a payment fails
- Cancel and everything keeps working until the end of the period you paid for.
- If a payment fails, bring-your-own-AI keeps working and sync stops. Nothing is deleted.
- Your data stays on each device either way — sync is a copy, not the original.
On Android
The same subscription is bought inside the Android app through Google Play. One subscription covers every platform, so buy it wherever is convenient — not twice.

Frequently Asked Questions
What does Cloud Sync actually sync?
What the AI has learned: importance scores and classifications, your prompts, and translations. It never syncs your emails, your accounts, your passwords or your contacts — those stay where they already are. Everything is end-to-end encrypted, so we hold ciphertext we cannot read. You pair a device with a QR code or a 24-word recovery phrase.
What is a credit, and how many do I get?
One credit pays for one AI request — scoring one email, one translation, one suggested draft. If the request fails, the credit comes straight back. Every install starts with 500 credits and receives 20 more every week, forever. Credits do not expire.
Is my data private?
Your mailbox lives in a local database on your own device and we never keep a copy. When the AI runs on Saymail Cloud credits, the text of the message being classified is sent through our proxy to the model provider — that is exactly what the credit pays for, and we use Zero-Data-Retention models. Point Saymail at a local model instead and nothing leaves your machine at all. Optional diagnostics can be turned off in settings.
How many devices can I use?
The free app installs on as many machines as you like. A bring-your-own-AI licence covers 5 activations, and you can deactivate a device you no longer use. A Cloud Sync subscription covers every device you pair with it.
