What the account does
Licensing stays separate from writing.
Your passwordless account verifies the trial, purchase, and device activations. It is not a document store, and Syncphonia does not upload your Markdown library to activate the app.
Use your own devices
Register up to 10 devices to one personal account, and manage those activations from the account page.
Keep ordinary files
Your license changes access to the app, not the format or ownership of the Markdown files on your disk.

Pricing questions
When does the trial begin?
The 15-day trial begins when your passwordless account is verified and the trial is activated. It runs for 15 consecutive days.
Do I need a credit card for the trial?
No. A verified email account is required, but no card is collected to start the trial.
Can I buy before the trial ends?
Yes. Buy anytime during the trial from your account page. Your one-time license activates as soon as payment is confirmed.
Is $9.99 a subscription?
No. It is a one-time USD price for the individual Syncphonia license described here. Applicable taxes, if any, are shown before payment.
What counts toward the 10-device limit?
Each activated installation counts as one device. You can review and remove device activations from your account.
Can I keep writing offline?
Yes. A paid activation normally keeps editing available offline for up to 60 days after its latest online renewal. Syncphonia checks locally on ordinary launches and connects only when renewal is due.
What happens when the trial ends?
Syncphonia stays available in read-only mode, and your Markdown files remain ordinary files on your device. Buy once whenever you are ready to restore editing.
