Terms of Service

Effective date: April 10, 2026

These terms constitute a binding agreement between you and Free Invoice Maker ("freeinvoicemaker.app"), operated by adpena ("we", "us", "our"). By accessing or using the service at https://freeinvoicemaker.app, you agree to these terms. If you do not agree, do not use the service.

1. Description of Service

Free Invoice Maker is an invoicing tool that runs on Cloudflare Workers. Anonymous users may create, edit, and manage invoices entirely in the browser using local storage (IndexedDB). No account is required for local-only use. Registered users may optionally sync data to our cloud infrastructure. The service supports EU e-invoicing standards across seven jurisdictions. Optional AI-powered features (OCR, data extraction) are available on an opt-in basis and are processed via Cloudflare Workers AI.

2. Account Registration

Account creation is optional. If you register, you authenticate via magic-link email. We do not store passwords. You are responsible for maintaining access to the email address associated with your account. You must provide accurate information and promptly update it if it changes. You may not create accounts for the purpose of abusing the service, impersonating others, or circumventing usage limits.

3. Plans and Billing

The service offers a free tier and paid subscription tiers at $7, $15, and $39 per month (USD). Payments are processed by Stripe. Subscriptions renew automatically each month unless cancelled before the renewal date. You may cancel at any time through your account settings; cancellation takes effect at the end of the current billing period. Refunds are issued at our discretion and generally provided only for billing errors or service outages exceeding 72 consecutive hours. We reserve the right to change pricing with 30 days' written notice. The service also supports x402 micropayments via USDC on the Base network for programmatic API access; these payments are non-refundable once confirmed on-chain.

4. Acceptable Use

You agree not to:

• Use the service for any unlawful purpose or to facilitate fraud, money laundering, or tax evasion.
• Generate invoices that misrepresent goods or services, or create fictitious invoices.
• Attempt to gain unauthorized access to other users' data, accounts, or our infrastructure.
• Reverse-engineer, decompile, or disassemble any part of the service, except where permitted by applicable law.
• Transmit malware, viruses, or any code designed to disrupt or damage the service.
• Use automated systems (bots, scrapers) to access the service in a manner that degrades performance for other users, except through our published API with valid credentials.
• Resell, sublicense, or redistribute the service without our prior written consent.

5. Your Data and Content

You retain full ownership of all invoices, client data, and other content you create or upload. We do not claim any intellectual property rights over your content. We access your data only to provide the service, enforce these terms, or comply with legal obligations. For local-only users, your data never leaves your browser. For cloud-synced users, data is stored on Cloudflare D1 (encrypted at rest) and Cloudflare R2. You may export or delete your data at any time. See our Privacy Policy for details on data handling.

6. AI Features

AI features such as OCR and invoice data extraction are strictly opt-in. When you use these features, your input data is processed by Cloudflare Workers AI. We do not use your data to train AI models. AI output is provided as-is and may contain errors. You are responsible for reviewing and verifying any AI-generated content before relying on it for business or legal purposes.

7. API and Agent Access

The service provides programmatic API access for autonomous agents. API calls may be paid via x402 micropayments (USDC on Base). You are responsible for all activity performed through your API credentials or wallet. Rate limits apply and may be adjusted at our discretion. We reserve the right to suspend API access for abuse or excessive usage.

8. Third-Party Services

The service integrates with third-party providers: Stripe for payment processing, Cloudflare for hosting and data storage, Resend for transactional email delivery (invoices, magic links, payment reminders), and the Base network for x402 micropayments. Your use of these services is subject to their respective terms and privacy policies. We are not responsible for the availability, security, or conduct of third-party services.

9. Disclaimer of Warranties

The service is provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or free of harmful components. We do not guarantee that invoices generated by the service will satisfy the legal or regulatory requirements of any particular jurisdiction. You are solely responsible for ensuring compliance with applicable invoicing laws.

10. Limitation of Liability

To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity arising out of or related to your use of the service. Our total aggregate liability for any claims arising under these terms shall not exceed the greater of (a) the amount you paid us in the twelve months preceding the claim, or (b) fifty US dollars ($50). Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded by law.

11. Indemnification

You agree to indemnify, defend, and hold harmless adpena and its officers, employees, and agents from any claims, damages, losses, or expenses (including reasonable legal fees) arising out of your use of the service, your violation of these terms, or your violation of any applicable law or the rights of a third party.

12. Termination

You may stop using the service and delete your account at any time. We may suspend or terminate your access if you violate these terms, engage in abusive behavior, or if required by law. Upon termination, your right to use the service ceases immediately. We will make your data available for export for 30 days following termination, after which it may be permanently deleted. Sections 5, 9, 10, 11, and 14 survive termination.

13. Changes to Terms

We may update these terms from time to time. Material changes will be communicated via email (for registered users) or by posting a notice on the service at least 14 days before the changes take effect. Continued use of the service after the effective date constitutes acceptance. If you disagree with the updated terms, you may terminate your account.

14. Governing Law and Disputes

These terms are governed by and construed in accordance with the laws of the State of California, United States, without regard to conflict of law principles. Any disputes arising under or in connection with these terms shall be resolved in the state or federal courts located in San Francisco County, California. If you are an EU consumer, nothing in this section overrides your right to bring claims in your local courts under mandatory consumer protection law.

15. Severability

If any provision of these terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
