Terms of service

Effective October 2, 2026 · Covers the Perkival browser extension, the perkival.com website, and the required Perkival account service (together, "the Service").

Readable summary (not a substitute for the terms): Perkival is beta software that shows you your own card-benefit data. It never holds your bank credentials. It's an informational tool, not financial advice — verify amounts with your issuer before making money decisions. You're responsible for your own agreements with your card issuers. Beta software comes as-is.

1. Who we are, and agreement to these terms

The Service is operated by Perkival Inc. By installing the extension, creating an account, or using the website, you agree to these terms. If you don't agree, don't use the Service.

2. What the Service is (and isn't)

3. Your bank relationship stays yours

4. Your account and your data

5. Acceptable use

You agree not to:

6. Beta software — warranty disclaimer

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT BENEFIT DATA IS ACCURATE, COMPLETE, OR CURRENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.

7. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST CREDITS, MISSED BENEFITS, EXPIRED REWARDS, ISSUER ACTIONS ON YOUR ACCOUNTS, OR LOST PROFITS, ARISING FROM USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AND US $50.

8. Price

Free is free of charge for 1 login and up to 2 cards. Free stays free. Plus is $40/yr, and continued use of any paid feature will require your explicit agreement — nothing converts to paid silently. Plans are Active or Cancelled; there is no pause. Promo codes can grant Plus for a period.

9. Termination

You can stop using the Service at any time; uninstalling the extension and deleting your account removes your relationship with us. We may suspend or terminate access for breach of these terms or to protect the Service, and we may discontinue the beta. Export to CSV or Excel is a Plus feature; any user can request access to their data under the Privacy Policy.

10. Changes to these terms

Material changes will be announced in the product and on this page with a new effective date before they apply.
