Terms of sale and use

1. What you're buying

When you purchase Paidlio, you receive a personal, perpetual licence to install and use the Paidlio desktop application on the computers you work on yourself. You may continue to use the version you have indefinitely.

2. One person, the computers you work on

The licence is for one person (you) to use on the computers you work on yourself, a desktop and a laptop for instance. You may:

• Install it on each computer you work on yourself.
• Move your installation to a new computer when you replace one.
• Make backups of your installed files for your own use.

You may not:

• Share your licence key with anyone else.
• Resell, sublicense, or redistribute the software.
• Use the software to provide invoicing services to third parties as a hosted offering.
• Reverse engineer, decompile, or disassemble the software (except where local law expressly permits this and we cannot waive it).

3. Licence keys, validated locally after activation

The first time you enter your licence key on a computer, Paidlio makes one HTTPS call to our payment provider, Lemon Squeezy, to register the activation. That call carries the key and the computer's name, and the result is stored on that computer. From then on the licence is verified locally. Paidlio never checks in to keep the licence valid and sends no hardware fingerprint, and your activated copy will continue working even if we cease operations. Releasing a computer in Settings makes one further HTTPS call to free its activation. Apart from those, the app goes online only for updates, and only if you let it. It checks for a new version when it starts, which you can switch off in Settings, and downloads a new version when you click Install update.

4. Payment and delivery

All purchases are one-time payments processed by Lemon Squeezy, our merchant of record. As soon as your payment goes through, Lemon Squeezy emails your receipt and licence key, usually within a few minutes, and you download Paidlio from paidlio.com, or on Windows install it from the Microsoft Store. Keep your licence key safe. We can re-issue it on request, but treat it like a key to a small lockbox.

5. Updates

Updates are released at our discretion and made available to existing customers. They contain bug fixes, security patches, new features, and platform compatibility improvements. You may continue using any installed version indefinitely.

6. Support

Email support is included with your licence. We aim to reply within one business day. Support covers installation help, configuration, and reasonable how-to questions. It does not cover bookkeeping advice, accounting interpretations, or third-party tools.

7. Refunds

We offer a 14-day refund from the date of purchase. No questions, no forms, no friction, just email us via the contact form and we'll process it. Once refunded, please uninstall the software. Refunds are not available after 14 days, except where required by law.

8. Your data is yours

Paidlio is a local application. Your customer records, invoices, payments, and other content are stored locally on your machine. You own that data outright. We do not have a copy. Backing it up is your responsibility, though Paidlio includes scheduled backup tooling to make this easy.

9. Scope of the software

Paidlio is invoicing software, not accounting software. It does not produce profit & loss statements, balance sheets, trial balances, tax filings, or financial statements suitable for statutory submission. It does not constitute professional accounting, legal, or tax advice. You remain responsible for your bookkeeping and tax obligations, ideally with a qualified accountant.

10. Warranty disclaimer

Paidlio is provided "as is", without warranty of any kind beyond the rights granted by your local consumer protection law. We do not warrant that the software will be error-free, meet your specific requirements, or be uninterrupted in operation. Use it carefully, and keep backups.

11. Limitation of liability

To the maximum extent permitted by law, our total liability for any claim arising out of these terms or your use of the software is limited to the amount you paid for your licence. We are not liable for indirect, incidental, or consequential damages, including loss of data or business interruption.

12. Termination

This licence continues until terminated. We may terminate if you materially breach these terms (e.g. share your key publicly, resell the software). On termination you must stop using the software, but your data remains yours. Sections 8 through 13 survive termination.

13. Governing law

Your purchase of Paidlio is processed by Lemon Squeezy as merchant of record, and the sale itself is governed by their terms and the law of their jurisdiction. Beyond the sale, the mandatory consumer protection laws of the country where you live continue to apply to you and are not displaced by these terms. We will deal with any dispute in good faith and aim to resolve it informally before any formal proceedings.

14. Changes to these terms

If we change these terms, the "last updated" date at the top will change. Material changes will be announced on the homepage. Your existing licence is governed by the terms in force at the time you purchased it.
