Terms of Service

These terms cover your purchase and use of Tabiya, a desktop chess database application, together with the Gigabase game archive and any update subscription. Tabiya is made by Tabiya ("we", "us"). By buying or using Tabiya you agree to these terms.

Who processes your payment

Payments are handled by Stripe through its Link service, which acts as the merchant of record. Your card statement will show a charge from LINK.COM* TABIYA. Stripe calculates and collects any sales tax or VAT, sends your receipts and handles payment questions. Stripe's own terms apply to the payment itself.

What you get

A one-time purchase gives you a permanent license to use the version of Tabiya you bought, plus your Gigabase archive. That is Gigabase Core (games from 2000 onward) or Gigabase Complete (the full archive), depending on what you buy. It does not include future updates to either the software or the archive. Those come with an update subscription, described below.

Your license

• Your license is personal. You may install Tabiya on up to 2 computers that you own or use.
• You may not share, resell, sublicense, or publicly redistribute Tabiya, your license key, or the Gigabase archive, in whole or in substantial part.
• The Gigabase archive is built on Lumbra's Gigabase and is licensed to us for distribution with Tabiya. Your own games, notes and analysis belong to you.
• You may not reverse-engineer the license check or bypass it.

Update subscription

The update subscription costs $7 per month or $60 per year, plus any tax. It gives you each monthly Gigabase update and new versions of Tabiya while it is active.

• It is optional. Tabiya and your archive keep working without it. They just stop receiving updates.
• If you choose a subscription when you buy Tabiya, your first subscription charge is one month after your purchase date, and it then renews on the same day each month (or each year). You'll get an email reminder before the first charge.
• It renews automatically until you cancel. You can cancel at any time from your Link account at app.link.com, or by emailing us. Cancelling stops future charges, and you keep updates until the end of the period you've already paid for.
• If you resubscribe after cancelling, you receive the current update from that point on. Updates released while you weren't subscribed are not included.

Prices

Prices are in US dollars and may change for new purchases. If we change the price of an active subscription, we'll tell you by email at least 30 days before it takes effect, and you can cancel before then.

Refunds

See our Refund Policy.

Internet connection

Tabiya needs an internet connection to activate your license, download your archive and install updates. It checks your license periodically. Chess analysis and browsing your database work offline.

No warranty

Tabiya is provided "as is". We work hard to make it reliable, and game data comes from many public sources that may contain errors. To the extent the law allows, we make no warranties about Tabiya beyond those stated here. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim.

Ending your license

If you break these terms, for example by sharing your license key publicly, we may deactivate your license. A refunded or charged-back purchase also ends the license.

Changes and governing law

We may update these terms and will post the new version here with a new effective date. These terms are governed by the laws of Tennessee, USA.
