Terms of Service

Effective Date: February 5, 2026  ·  Last Updated: February 5, 2026

These Terms of Service ("Terms") govern your use of the RoofingPro mobile application ("the App") operated by KostaApps ("we", "our", or "us"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. Eligibility

You must be at least 18 years old (or the legal age of majority in your jurisdiction) to use the App. By using the App, you represent and warrant that you meet this requirement.

2. Description of Service

RoofingPro is a roofing estimation tool designed for contractors. The App allows you to:

• Calculate roofing project costs based on dimensions, materials, labor, and other variables.
• Generate and share professional PDF estimates.
• Save quotes and customer information locally on your device.
• Customize settings including tax rates, profit margins, and currency.

3. Estimates and Accuracy

The App provides estimates only. All calculations are based on average regional pricing data, standard conditions, and the inputs you provide. Actual project costs may vary significantly based on:

• Local material and labor prices.
• Site-specific conditions (structural damage, access difficulty, code requirements).
• Material availability and supplier pricing.
• Seasonal factors and market conditions.

You are solely responsible for verifying all estimates before presenting them to clients, obtaining permits, or entering into contracts. We do not guarantee the accuracy, completeness, or fitness of any estimate for any particular job.

4. Accounts and Data

The App does not require account registration. All data (estimates, business information, customer details, and settings) is stored locally on your device. You are responsible for maintaining backups of your data. We are not responsible for data loss resulting from device failure, app uninstallation, or any other cause.

5. Subscriptions and Payments

5.1 Free and Pro Tiers

The App offers a free tier with limited features and a paid "RoofingPro Pro" subscription that unlocks additional functionality including unlimited saved estimates and PDF generation.

5.2 Payment Processing

All payments are processed through Apple's App Store or Google Play Store. By subscribing, you agree to their respective payment terms. We do not directly process or store your payment information.

5.3 Subscription Terms

• Subscriptions automatically renew at the end of each billing period unless cancelled at least 24 hours before the end of the current period.
• You can manage or cancel your subscription through your device's App Store or Play Store settings.
• Refunds are handled by Apple or Google according to their respective refund policies.

5.4 Price Changes

We reserve the right to change subscription pricing at any time. Price changes will not affect your current billing period and will take effect at the next renewal. You will be notified of price changes through the app store.

6. Acceptable Use

You agree not to:

• Use the App for any unlawful purpose or in violation of any applicable laws or regulations.
• Reverse engineer, decompile, disassemble, or attempt to derive the source code of the App.
• Modify, adapt, translate, or create derivative works based on the App.
• Remove, alter, or obscure any copyright, trademark, or other proprietary notices.
• Use the App to generate fraudulent, misleading, or deceptive estimates.
• Circumvent, disable, or interfere with security features of the App.

7. Intellectual Property

The App, including its code, design, content, icons, and branding, is owned by KostaApps and protected by copyright, trademark, and other intellectual property laws. These Terms do not grant you any rights to our intellectual property except a limited, non-exclusive, non-transferable, revocable license to use the App for its intended purpose.

The estimates, PDFs, and documents you create using the App belong to you.

8. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that:

• The App will be uninterrupted, error-free, or free of viruses or other harmful components.
• The estimates produced will be accurate for any specific project.
• The App will meet your specific requirements.
• Any defects will be corrected.

• Loss of profits, revenue, data, or business opportunities.
• Cost overruns or losses resulting from reliance on estimates generated by the App.
• Damages arising from disputes between you and your clients.
• Losses from inaccurate calculations or pricing data.

IN NO EVENT SHALL OUR TOTAL LIABILITY EXCEED THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.

10. Indemnification

You agree to indemnify, defend, and hold harmless KostaApps, its owners, employees, and affiliates from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising from your use of the App, your violation of these Terms, or your violation of any third-party rights.

11. Third-Party Services

The App integrates with third-party services (RevenueCat, Apple App Store, Google Play Store) that have their own terms and privacy policies. Your use of these services is governed by their respective terms, and we are not responsible for their practices or content.

12. Modifications to the App and Terms

We reserve the right to modify, suspend, or discontinue the App (or any part of it) at any time without notice. We may also update these Terms from time to time. Changes will be posted on this page with an updated effective date. Your continued use of the App after changes constitutes acceptance of the revised Terms.

13. Termination

We may terminate or suspend your access to the App at any time, without prior notice, for conduct that we believe violates these Terms or is harmful to other users, us, or third parties. Upon termination, your right to use the App ceases immediately.

14. Governing Law

These Terms are governed by and construed in accordance with the laws of the Province of Ontario, Canada, without regard to conflict of law principles. Any disputes arising under these Terms shall be resolved in the courts of Ontario, Canada.

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.

16. Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and KostaApps regarding your use of the App and supersede all prior agreements and understandings.
