End-User Licence Agreement

Last updated: 25 October 2026

1. Parties and licence

This agreement is between Blyvon, N92, Mayfield Garden, Sector 51, Gurgaon, Haryana, India (“Blyvon”) and the person using Blyvon Books (“you”). Blyvon grants its staff, and client reviewers it has invited, a limited, non-transferable, revocable licence to use Blyvon Books for bookkeeping work and review. By using the platform you accept these terms.

2. Authorisation to connect accounts

When you connect a QuickBooks Online, Xero, Gmail or Outlook account, you confirm that you are authorised to do so and to let Blyvon Books read the data in it, and to make changes that are approved within the platform: for ledgers, the approved entries; for mailboxes, sending the replies, portal invitations and statement requests that a user has approved.

3. Acceptable use

Use the platform only for lawful purposes and only for the clients and work you are assigned to.
Do not try to access data that belongs to someone else or that you have not been given access to.
Do not interfere with, probe or overload the platform, or copy or reverse engineer it.
Keep your password and two-factor sign-in private, and tell us at once if you think they have been exposed.

4. Your data

Clients own their data. Blyvon processes it only to provide the service. How we handle data is described in our Privacy Policy.

5. Third-party services

The services you connect (Intuit QuickBooks Online, Xero, Google and Microsoft) are governed by their own terms, which also apply to your use of them. Their availability and behaviour are outside our control.

6. Changes to the service

The platform may change over time, including its features, the connected services it supports and how they work.

7. No warranty and limit of liability

Blyvon Books is provided “as is”. To the extent the law allows, Blyvon gives no warranty that it will be uninterrupted or error-free, and it is not liable for indirect or consequential loss, or for losses caused by the connected third-party services. Suggestions made by the platform, including automated categorisations, must be reviewed by a qualified person. Nothing in this agreement limits liability that cannot be limited by law.

8. Termination

Blyvon may suspend or withdraw access at any time, for example when a person leaves the firm or an engagement ends. You may stop using the platform at any time. A connected QuickBooks Online or Xero company can be disconnected from within the platform by the firm’s Owner or the client’s assigned manager, a connected mailbox or Slack by writing to info@blyvon.com, and any connection can be removed from within the connected service itself.

9. Governing law

This agreement is governed by the laws of India. The courts at Gurugram, Haryana, have jurisdiction over any dispute arising from it.
