S-902 Legal

Terms of service and end user licence

The short version: you get a licence to use AREZ as a design aid, you remain the engineer responsible for what you issue, and you can cancel any time.

Last updated November 8, 2026

1. Agreement

These terms are between you and Taktek. By installing or using AREZ, or by buying a seat on tryarez.com, you accept them. If you buy for a firm, you confirm you can bind the firm.

2. Licence

We grant you a non exclusive, non transferable licence to install and run AREZ on computers you control, for one engineer per seat, while your subscription is active. Firm plans may move a seat between engineers; a seat may be used by one person at a time.

3. Engineering responsibility

AREZ is a design aid. It applies the code provisions and product data described in the documentation, and it shows its assumptions on the sheets. It does not replace the judgment of a licensed engineer. You are responsible for reviewing every result, for the applicability of the codes to your project, for the loads and site conditions you enter, and for every drawing you seal and issue. AREZ does not design foundations; it reports loads at bearing points for the foundation engineer.

4. Trial and preliminary stamp

The free trial lasts 14 days, needs no card, and includes every feature. Sheets produced during the trial carry a PRELIMINARY stamp and may not be issued for construction. The stamp is removed on licensed seats, and sheets then read NOT FOR ISSUE until you, the engineer of record, clear that flag.

5. Billing and cancellation

Subscriptions are billed through Stripe, yearly or monthly, in US dollars, at the price shown at checkout. The founding price is locked for as long as the subscription stays active without interruption: the founding price applies to the first 100 seats, yearly or monthly, and never rises while the subscription stays active without interruption. You can cancel in one click from your billing page; access continues to the end of the paid period and nothing more is charged. Refunds are covered by the refund policy. Prices for new seats may change; we give at least 30 days' notice before a renewal price changes.

6. Updates and code editions

Updates, including new code editions and product data catalogs, are included while your subscription is active. We do not promise a date for any specific edition. Older projects keep the edition they were designed to until you choose to update them.

7. Product data and trademarks

AREZ uses published catalog data from manufacturers such as Simpson Strong-Tie. Those names and products are trademarks of their owners, who are not affiliated with AREZ and do not endorse it. Always confirm a product against the current manufacturer catalog before specifying it.

8. Restrictions

9. Warranty and liability

We work hard to make AREZ correct, and we publish known issues in the changelog. Still, the software is provided as is. To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability is limited to the amount you paid in the twelve months before the claim. Nothing here limits liability that cannot be limited by law.

10. Governing law

These terms are governed by the laws of Lebanon, and disputes go to the courts of Beirut, Lebanon. If a clause is found invalid, the rest stays in force. Questions: hello@tryarez.com.
