EtherPK Pricing

Two plans. Your notes are yours on both.

EtherPK is free to use for local folder based graphs on your computer. Sync+ enables sync between all of your devices (with optional mirroring and export to local), generous storage limits for large graphs, and multiplayer editing.

  • Run the source-available Client on your own computer A Node bundle or a Docker image, for folder graphs with no account and no EtherPK service involved.

Questions about Sync+

What happens when the trial ends?
Sync+ renews automatically and your card is charged US$9.99 for the next month, and every month after that, until you cancel. Cancel before the trial ends and you pay nothing. Each account gets one trial.
How do I cancel?
On the Billing page, Payment details opens Stripe's billing portal, where you cancel. Cancelling stops the next renewal, and you keep Sync+ until the end of the period you have paid for.
Do you give refunds?
Not for part of a period. If you live in the UK and use EtherPK outside your business, you have 14 days from starting a subscription to change your mind, as the Terms set out.
What happens to my graphs if Sync+ ends?
The graphs you own become read-only: you and the people you shared them with can still open them, and you can export and delete them, but nobody can change them. Starting Sync+ again makes them writable. After a retention period we may delete graphs that stay read-only, so keep a local copy of anything you want to keep. Your local folder graphs are never touched.

The Terms set all of this out in full.
