Terms of Service

Last updated: September 6, 2026

1. About IterArc

IterArc is a personal life management Android application developed by Barnabás Tóth ("Developer"), an independent developer based in Budapest, Hungary. By using the app or website, you agree to these terms.

2. The Service

IterArc provides:

• Habit tracking with science-based behavior change methodology
• AI-powered food and nutrition tracking via photo analysis
• Intermittent fasting window tracking
• Weight and health goal analytics
• Household sharing (shopping lists, recipes, settings)
• Daily coaching briefings (morning plan, evening wrap)
• Bank account integration for financial tracking, via a licensed PSD2 account information service provider
• An in-app AI coach that can read and change your data on your instruction

The service is currently in beta. Features may change, be added, or be removed without notice.

3. Account & Authentication

• You must sign in with a Google account. No other authentication methods are currently supported.
• You are responsible for maintaining the security of your Google account.
• One user per Google account. Multiple Google accounts may join the same household.

4. Free of Charge

IterArc is free to use. There are no paid tiers, subscriptions, in-app purchases, or advertisements. The Developer reserves the right to introduce paid features in the future, but existing free features will remain free.

5. Your Data

• You own your data. We do not claim any ownership rights over your content (food photos, habits, notes, recipes, financial data).
• You grant us a limited license to process your data as described in the Privacy Policy.
• You can request deletion of all your data at any time by contacting [email protected].

6. AI-Powered Features

• Food photo analysis uses Google Gemini to estimate nutritional content. These estimates are approximations and should not be used as medical or dietary advice.
• Transaction categorization uses AI to classify spending. Categories may be inaccurate and can be manually corrected.
• The AI coach can create, change, and delete your data when you ask it to. Actions we classify as destructive ask you to confirm first, but you remain responsible for what you instruct it to do.
• All of these run on a server-side Google Gemini credential we pay for. There is no per-user API key and no charge to you. We apply per-user daily and weekly usage limits; heavy use may be throttled.
• AI outputs are provided "as is" without guarantee of accuracy. Do not rely on IterArc for medical, nutritional, or financial decisions without consulting a qualified professional.

7. Health Disclaimer

IterArc is not a medical device. It is a personal tracking tool. Information provided by the app — including calorie estimates, weight trends, fasting status, and daily briefings — is for informational purposes only. It does not constitute medical advice, diagnosis, or treatment.

Always consult a healthcare professional before starting a new diet, fasting protocol, or exercise program. If you have an eating disorder or disordered eating patterns, please consult a professional before using food tracking features.

8. Financial Disclaimer

The bank integration provides a read-only view of your transactions for personal budgeting purposes. IterArc is not a financial advisor. Transaction categorization and budget tracking are informational tools. Do not make financial decisions based solely on data in IterArc.

9. Household Sharing

• When you invite someone to your household, they can see your habits, food entries, shopping lists, shared recipes, and household settings.
• You are responsible for who you invite. Household invites are code-based and expire after 7 days.
• The household owner can remove members. Removed members lose access to shared data immediately.

10. Acceptable Use

You agree not to:

• Use the app for any illegal purpose
• Attempt to access other users' data outside your household
• Reverse-engineer, decompile, or extract the source code of the app
• Use automated tools to scrape or abuse the service
• Upload harmful, illegal, or inappropriate content via food photos or notes

11. Service Availability

IterArc is provided "as is" without warranty. The Developer does not guarantee:

• Uninterrupted service availability
• Accuracy of AI-generated nutrition estimates
• Preservation of data in case of service discontinuation

The app requires an internet connection. Every entry is written straight to the server; there is no offline write queue. If a save fails, the app tells you so at the time rather than storing the entry for later. When the service is unavailable, you cannot log anything.

12. Limitation of Liability

To the maximum extent permitted by law, the Developer shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of IterArc. This includes but is not limited to: health outcomes based on nutrition estimates, financial losses based on budget tracking, or data loss due to service interruption.

13. Beta Software

IterArc is currently in beta. This means:

• Bugs may exist. Please report them.
• Features may change without notice.
• Data migration between versions is best-effort.
• The app is distributed as a debug APK, not via Google Play Store (Play Store listing is planned).

14. Open Source

The IterArc source code is available on GitHub. The app's license terms apply to source code usage separately from these Terms of Service for end users.

15. Governing Law

These terms are governed by the laws of Hungary. Any disputes shall be resolved in the courts of Budapest, Hungary.

16. Changes

We may update these terms when features change. The "last updated" date will be updated. Continued use of the app after changes constitutes acceptance.
