Terms of Service

1. What the App Does

Offline Invoice Maker is an offline-first mobile productivity utility designed to create and manage invoices, estimates, client directories, and catalog line items, render PDF documents locally, and export JSON database backups and CSV spreadsheets. All operational data is stored strictly on your personal device.

2. End-User License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on mobile devices you own or control, solely for your legitimate business purposes, subject to standard Apple App Store and Google Play terms of service. You may not reverse-engineer, decompile, disassemble, resell, or distribute the App or its underlying source code except as expressly authorized by applicable store policies.

3. Pro Purchases and Subscriptions

• Pro Offerings: Pro upgrades may be offered as a one-time lifetime unlock license or auto-renewing periodic subscriptions (monthly or yearly), as presented on the in-app purchase paywall.
• Payment Processing: Payments are processed directly through the Apple App Store (iOS) or Google Play (Android) and managed via RevenueCat. Prices are determined by regional store tiers and include applicable local sales taxes.
• Auto-Renewal: Subscriptions automatically renew unless cancelled at least 24 hours prior to the conclusion of the active billing period via your Apple ID or Google Play account subscription settings.
• Lifetime License: A one-time lifetime license confers perpetual Pro access tied to your Apple ID or Google Play account, usable across devices linked to that account.
• Restore Purchases: You may restore your active license or lifetime unlock anytime in the App via Settings > Restore Purchases.
• Refunds: In-app purchase refunds are handled exclusively by Apple or Google under their respective store refund guidelines. As a developer, we have no mechanism to issue store refunds directly.

4. Your Data — Your Responsibility

You retain complete ownership over all documents, records, client information, and line items entered into the App:

• We never receive or monitor your business documents (see our Privacy Policy).
• Regular Backups: Because data is stored strictly in your device's local storage, you are solely responsible for creating regular JSON database backups and exporting copies via Settings > Backup & Restore.
• Uninstalling the App or wiping your device without an external backup permanently erases your records.
• You bear sole legal responsibility for the accuracy of invoices, totals, rates, and tax calculations issued to your clients.

5. Acceptable Use

You agree not to use the App for fraudulent, deceptive, or illegal billing activities; to create false or counterfeit invoices; to infringe on proprietary trademarks or copyrights; or to attempt to bypass in-app purchase verification.

6. Intellectual Property

The App, its codebase, typographic PDF rendering engine, 170+ template architectures, and branding are the proprietary intellectual property of Chronos Labs. Your invoice contents, uploaded company logos, and client data remain exclusively yours.

7. Availability and Updates

Because the App operates completely offline, core features do not rely on server uptime. We may issue updates to improve performance, fix software anomalies, or adapt to operating system requirements. Pro features previously purchased will remain accessible in accordance with store records.

8. Third-Party Services

Store billing (Apple, Google, RevenueCat) and system functions (OS share sheet, device camera, photo picker, storage sandboxes) are governed by the respective providers' terms and conditions. We are not liable for third-party downtime or policy modifications.

9. Disclaimer of Warranties

The App is provided on an "as is" and "as available" basis, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular commercial purpose, or uninterrupted operation. Please consult our Disclaimer for specific tax and legal guidelines.

10. Limitation of Liability

To the maximum extent permitted by applicable law, Chronos Labs shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data corruption, or business interruption arising out of your use of the App. Total cumulative liability is strictly limited to the amount paid by you for the App in the 12 months preceding the claim.

11. Termination

You may terminate this agreement at any time by deleting the App and all associated backups. We reserve the right to suspend or revoke license access for clear violations of these terms or store policies.
