Terms of Use

FractalFlow for Mac, iPhone and iPad · Effective September 25, 2026

These Terms are an agreement between you and Benjamin Rizkin, doing business as Rizkin Labs, Winston-Salem, North Carolina, USA ("Rizkin Labs", "we", "us"), for the FractalFlow app distributed through the Apple App Store. By downloading or using the app you agree to these Terms. If you do not agree, do not use the app.

These Terms apply together with Apple's Licensed Application End User License Agreement (the "Standard EULA"). If the two conflict, these Terms apply to the extent the Standard EULA allows.

1. The app

FractalFlow is project-scheduling software. It calculates critical paths, dates, costs, earned value and, on the Studio plan, schedule-risk simulations from the information you enter. These results are estimates. Check them before you rely on them for contracts, bids, commitments or safety-critical work.

2. Your licence

We grant you a personal, non-exclusive, non-transferable licence to use the app on Apple devices that you own or control and that are signed in with your Apple Account, as permitted by the Standard EULA and for as long as your trial or subscription is valid (Viewer mode, described below, remains available after that). We keep all other rights.

You may not copy, resell or redistribute the app, reverse engineer it (except where the law does not allow this restriction), or use it to build a competing scheduling product.

3. Free trial, subscriptions and renewal

A free 14-day trial of the Studio plan starts the first time you open the app. No purchase is needed to start it and nothing is charged when it ends.

After that, you can subscribe to one of these plans:

Prices are in US dollars. Apple shows the equivalent price in your local currency before you buy. One subscription covers Mac, iPhone and iPad.

• Payment is charged to your Apple Account when you confirm the purchase.
• Subscriptions renew automatically for the same period and price unless you cancel at least 24 hours before the end of the current period.
• Your account is charged for the renewal within the 24 hours before the current period ends.
• You can manage or cancel your subscription in your App Store account settings, or from FractalFlow: Settings, Subscription, Manage Subscription.
• Billing, refunds and payment disputes are handled by Apple under Apple's terms. Request a refund at reportaproblem.apple.com.

If we change a subscription price, Apple will notify you in advance as its rules require, and you can cancel before the new price applies.

4. Viewer mode

If you have no active trial or subscription, the app runs in Viewer mode. You can open, print and export your plans and save copies of them, but changes are not kept. Your plans remain yours and are never locked away.

5. Your content

You own the plans you create or import. We claim no rights in them and never receive them. You are responsible for having the right to use any file you import and for any confidentiality obligations that apply to its contents.

6. iCloud and sharing

Sync and sharing use Apple's iCloud, and Apple's terms apply to that storage. Sharing plans with other people requires the Studio plan. You decide who you share with and what permission they get, and you are responsible for the content you share. Shared plans are saved on a last-save-wins basis; they are not edited live by several people at once. Rizkin Labs does not keep a copy of your plans on its own servers.

7. Acceptable use

Do not use the app for anything unlawful, do not attempt to disrupt or break the app, and do not attempt to bypass its subscription checks.

8. File compatibility

The app can open Microsoft Project files (.mpp, Project 2007 and later), Project XML and CSV, and can export Project XML, CSV, images, PowerPoint files and PDFs. It does not write binary .mpp files. Compatibility is provided for convenience. FractalFlow is independent and is not affiliated with, endorsed by or sponsored by Microsoft or any other software vendor. Microsoft, Microsoft Project, PowerPoint and Excel are trademarks of the Microsoft group of companies.

9. Updates and support

We may update the app to fix problems, add features or meet legal requirements. Some features may change or be removed over time. Support is available at fractalflow.rizkinlabs.com/support and hello@rizkinlabs.com. Apple has no obligation to provide support for the app.

10. Disclaimer

The app is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that schedules, float, costs, earned-value figures or simulation results are accurate or complete, or that the app will be uninterrupted or error-free.

11. Limitation of liability

To the fullest extent permitted by law, Rizkin Labs will not be liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or business opportunities. Our total liability for all claims relating to the app is limited to the amount you paid for the app in the twelve months before the claim, or US $50 if you paid nothing.

Some jurisdictions do not allow these exclusions or limits. Where that is the case, they apply only to the extent the law allows, and nothing in these Terms limits rights you have as a consumer that cannot be waived.

12. Apple

These Terms are between you and Rizkin Labs, not Apple. Apple is not responsible for the app or its content, has no obligation to provide maintenance or support, and is not responsible for any claims relating to the app, including product-liability claims, claims that the app fails to meet a legal or regulatory requirement, consumer-protection claims, or claims that the app infringes someone else's intellectual property. If the app fails to meet any applicable warranty, you may notify Apple, and Apple may refund the purchase price; Apple has no other warranty obligation. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You confirm that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties.

13. Ending these Terms

You can stop using the app at any time. We may suspend or end your licence if you seriously breach these Terms. Sections 5 and 10 to 15 continue after these Terms end.

14. Changes to these Terms

We may update these Terms. We will change the effective date above and, for material changes, tell you in the app or its release notes. Continuing to use the app after a change takes effect means you accept the updated Terms. If you do not accept them, stop using the app and cancel your subscription.

15. Governing law and disputes

These Terms are governed by the laws of the State of North Carolina, USA, without regard to its conflict-of-law rules. The state and federal courts located in Forsyth County, North Carolina have exclusive jurisdiction over any dispute relating to the app or these Terms, and you and we consent to that jurisdiction. If you live outside the United States, you also keep any right your local law gives you to bring a claim in the courts where you live. Before starting any claim, please email us so we can try to resolve it informally.
