Terms of Service

The terms for using BillHeron, in the apps and on the website.

1. About these terms

These terms apply to the BillHeron apps for iPhone and Android and the website billheron.com (together, the "Service"), provided by ONERACK LTD. By using the Service, you agree to these terms. Please read them carefully.

2. Using the Service

BillHeron lets you create, edit and manage invoices, estimates and receipts. It's made for freelancers and businesses, and must not be used for anything illegal, fraudulent or misleading.

You're responsible for the documents you create, including that the amounts, taxes and details on them are correct. The Service helps you create documents, but doesn't check or certify them, and doesn't give tax or legal advice. In some countries, an official tax invoice must be issued through a government system; the Service doesn't replace that.

3. Offline use, accounts and sync

You can use the app fully offline, without an account. Your documents are then stored only on your device, and you're responsible for keeping them safe.

You can create an account by signing in with Apple or Google. When you turn on sync, your documents and related data are stored in your account so they're available on your other devices and on the website. You're responsible for everything that happens in your account, so keep your Apple or Google sign-in secure.

How we handle your data is explained in our Privacy Policy.

4. Free plan and Pro

Part of the Service is free. The free plan has limits, such as a limited number of documents and a small watermark on PDFs. Pro removes these limits.

Pro is a subscription that you can buy in the App Store, in Google Play or on the website. It renews automatically until you cancel it, and you can cancel it at any time where you bought it. After canceling, Pro stays active until the end of the period you've paid for. Prices are shown before you buy, and taxes may be added depending on where you are.

Purchases in the App Store and Google Play are handled by Apple and Google, and their refund rules apply. For purchases on the website, the rules of our payment provider and your legal rights as a consumer apply. Deleting your account doesn't cancel a subscription.

5. Your content

The documents and data you create are yours. You give us only the permission needed to store, sync and process them to provide the Service to you.

6. Our property

The BillHeron apps and website, including their design, templates, graphics and code, belong to ONERACK LTD and are protected by copyright and trademark law. You may not copy, modify, distribute or resell any part of them without our written permission. The PDFs you create with the templates are yours to use.

7. Availability and changes

We work to keep the Service available and improve it with updates. We may change, add or remove features, and parts of the Service may sometimes be unavailable, for example during maintenance.

8. Limitation of liability

The Service is provided "as is". We don't guarantee that documents created with it are legally valid or accepted for tax or accounting purposes in every country, and we're not responsible for the calculations, taxes or details you enter. Please check your documents before you send them.

To the extent the law allows, we're not liable for indirect damage, lost profits or lost data resulting from using the Service, or from not being able to use it. Nothing in these terms limits liability that can't be limited by law, or your rights as a consumer.

9. Ending your use

You can stop using the Service and delete your account at any time, in the app under Settings → Account → Delete account, or on the Delete account page.

We may suspend or close an account that breaks these terms or misuses the Service in a way that could harm others or us. Documents stored only on your device stay there.

10. Changes to these terms

We may update these terms for new features, changes in the law or improvements to the Service. Important changes will be announced in the app or on the website. If you keep using the Service after a change, the new terms apply.

11. Governing law

These terms are governed by the laws of the Republic of Cyprus. If you're a consumer, you keep the protection of the mandatory laws of the country where you live.
