Terms of use

These terms apply to the Deepline apps and the website deeplinechess.com, operated by [legal name], [address] ("we"). By using Deepline you agree to them.

What Deepline does

Deepline starts and stops chess engine servers in your own cloud provider account (Verda) and lets you use them from ChessBase, the Windows app and the Android app. It also shows live tournaments from the public Lichess broadcast service.

Your cloud account and its costs

You need your own Verda account. Verda bills you directly for every server hour; those charges are between you and Verda.
Deepline helps you control costs with a live cost meter, idle auto-stop, a maximum session length and confirmed server deletion. These features reduce the risk of unwanted charges, but they depend on your device, your network and Verda's service, and we cannot guarantee them. Check your Verda account regularly.
You are responsible for keeping your Verda credentials safe.

Plans and licenses

The Free plan is free of charge. Pro is a subscription, monthly or yearly; Founder is a one-time purchase of Pro for as long as Deepline is offered.
Purchases are made through Lemon Squeezy, our merchant of record, under its terms. You receive a license key by email.
A license may be used on up to 3 of your own devices. Do not share or resell it.
When a subscription ends or is cancelled, the key stops unlocking Pro at the end of the paid period.
Refunds: [refund policy].

Third-party software and data

The engine is Stockfish, free software under the GNU General Public License v3, which runs as a separate program. Live game data comes from Lichess (lichess.org) and is licensed by Lichess under its own terms. Deepline is not affiliated with Verda, Lichess, ChessBase or the Stockfish project.

No warranty, limitation of liability

Deepline is provided "as is". To the extent the law allows, we are not liable for indirect damages, lost games or data, or cloud provider charges, and our total liability is limited to the amount you paid us in the 12 months before the claim.

Changes and contact
