1. Parties and scope
These terms govern the relationship between Santix, which provides the Santix construction site and project management service (iPhone and iPad app, web panel and santix.app), and the organisation using the service and the users it invites. Santix is a business-to-business service, not a consumer product. The person who registers or buys for the organisation confirms they are authorised to bind it.
2. The service
Santix provides drawing upload and viewing, pins and notes on drawings, room data sheets, revision requests, scheduling, contract templates, procurement, budget and progress payments, document tracking and offline work. Features may evolve; we give notice before changes that materially reduce core functions.
3. Organisation account, roles and seats
- The service is provided per organisation. The organisation owner manages admins, roles and invitations.
- Every active user, including architects and subcontractors, uses one seat. When the seat limit is reached no new members can be added; existing members keep working.
- You keep your sign-in details confidential and are responsible, on your organisation’s behalf, for activity in your account.
4. Trial
Every new organisation starts with a 3-day trial. If no plan is chosen when it ends, the account becomes read-only; no data is deleted, and choosing a plan makes it writable again.
5. App Store subscription: price, renewal, cancellation and refunds
- Monthly plans (5, 10, 25 and 50 users) are auto-renewing App Store subscriptions. The organisation owner buys them in the app under Ayarlar › Plan ve ödeme (Settings › Plan and payment).
- The price is shown in the app and on the App Store before purchase, in your country’s currency, including taxes. Current monthly prices are on the pricing page.
- Payment is charged to your Apple Account when you confirm the purchase.
- The subscription renews automatically for the same period and price unless it is cancelled at least 24 hours before the end of the current period. The renewal is charged within the 24 hours before the period ends.
- You can manage or cancel the subscription in your App Store account settings (on iPhone: Settings › your name › Subscriptions). Cancellation takes effect at the end of the current period; you keep access until then.
- Because Apple collects the payment, refunds are requested from Apple under Apple’s rules (reportaproblem.apple.com). Santix cannot refund App Store payments directly.
- Upgrades apply immediately. Downgrades apply at the end of the period; if active users exceed the new limit nobody is suspended, but no new members can be added until you are under the limit.
- Deleting your account or the app does not cancel the subscription.
6. Annual plans, larger teams and invoiced deals
Annual plans, teams over 50 users and invoiced sales (bank transfer, Turkish e-invoice) are offered by written agreement through satis@santix.app. Payment, term and refund conditions are as stated in that agreement; these terms apply to anything it does not cover.
7. Acceptable use
Use the service lawfully. Do not upload content that infringes others’ rights, try to bypass security, reverse engineer the service or access it automatically by unauthorised means. You confirm you hold the necessary rights to the drawings, documents and photos you upload.
8. Your data
Content your organisation uploads and creates belongs to your organisation. Santix processes it only to provide the service and on your organisation’s instructions. See the privacy policy and the KVKK notice. When an organisation leaves the service we export its data on the admin’s request and then delete it.
9. AI suggestions, contract templates and calculations
AI suggestions, contract templates, tax and deduction rates and calculations help you decide; they are not legal, financial or engineering advice. Approving a suggestion, having a contract checked by your lawyer before signing and having rates checked by your accountant remain your responsibility.
10. Availability
We take reasonable care to keep the service available; maintenance, updates or third-party infrastructure failures may cause short interruptions. Records entered offline are kept on the device and sent when the connection returns; if a device is lost or the app is removed before syncing, unsent records may be lost.
11. Limitation of liability
To the extent the law allows, Santix’s total liability under these terms is limited to the fees the organisation paid for Santix in the 12 months before the event. Indirect loss, lost profit and loss caused by incorrect data entry are excluded. Liability for intent and gross negligence is not limited.
12. Intellectual property
The Santix software, design, templates and brand belong to Santix. During the subscription your organisation receives a non-transferable, non-exclusive right to use the service.
13. Suspension and termination
You can cancel at any time as described in section 5. We may suspend or end the service for serious breach of these terms, non-payment or a security risk, with prior notice where possible.
14. Apple-specific terms
If you downloaded the app from the App Store: these terms are between you and Santix, not Apple; Santix, not Apple, is responsible for maintenance and support; if the app fails to conform to any applicable warranty you may notify Apple, and Apple will refund the purchase price to the extent the law allows; Santix, not Apple, is responsible for product claims and third-party intellectual property claims relating to the app; Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. You confirm you are not located in a country under US embargo and are not on any list of prohibited parties.
15. Changes, governing law and contact
We publish new versions on this page with their date and announce important changes in the app or by email. Turkish law applies; the courts and enforcement offices of Istanbul (Central) have jurisdiction. Questions: destek@santix.app. This version is dated 13 November 2026.
