1. Provider and scope
The service is provided by Ali Talebpoor Amirhandeh trading as Ahura, Warnstedtstraße 57k, 22525 Hamburg, Germany, info@ahura.cloud. These terms apply to Sina's web application and related digital interfaces.
2. Product and deliverables
Sina is pathology reference and AI decision-support software intended for qualified professionals and trainees. Depending on the selected plan, it provides source search, structured review of de-identified case material, differential-diagnosis suggestions, IHC or ancillary-test prompts, comparison of AI-generated explanations, and editable bilingual report or reference drafts. Access is supplied digitally; no physical product is shipped. Features and fair-use limits shown for a plan form part of the order.
3. Eligibility, accounts and acceptable use
You must be at least 18 and able to enter into a contract. Keep your credentials secure and give accurate account information. You may not upload unlawful material, malware, confidential material you lack authority to use, or directly identifying patient data. You may not resell access, evade limits, scrape or reverse engineer the service, or present its unverified outputs as a final diagnosis or the sole basis for patient care.
4. Plans, prices and order information
Current public plans list Free at €0, Pro at €19 per month or an equivalent €15 per month when billed annually, and Clinic/Team at €79 per month or an equivalent €63 per month when billed annually. Taxes, the billing interval, included usage and the final total are displayed again before purchase and the checkout total controls if live pricing has changed. Usage units, where shown, measure access within Sina only: they are not money, cannot be redeemed for cash and are not transferable.
Sina currently uses the payment processor shown in checkout. Paddle is not represented as live on this service. It would be used only after domain approval and written product-category clearance.
5. Subscription, renewal and cancellation
A paid subscription renews for the interval displayed at checkout until cancelled. You can cancel before the renewal date through the billing interface or by emailing info@ahura.cloud. Cancellation stops future renewals; access normally continues to the end of the paid period. The receipt identifies the payment processor and merchant-of-record arrangement, if applicable.
6. Refunds and withdrawal
Our voluntary refund rules and instructions appear in the Refund Policy. Consumers may also have a statutory 14-day withdrawal right for distance contracts. Any request to begin a digital service during that period and any legally required acknowledgement will be collected separately at checkout. Mandatory consumer rights are not restricted.
7. Intellectual property
Ahura and its licensors retain rights in Sina, its design and software. You retain rights in material you submit and grant us a limited licence to process it only to provide, secure and support the service. Subject to third-party and source rights, you may use exported drafts for your own lawful educational or internal reference purposes.
8. Availability and responsibility
We work to keep the service available but do not promise uninterrupted access. Beta or third-party AI features can change or produce errors. Nothing excludes liability that cannot be excluded under German law, including liability for intent, gross negligence, injury to life, body or health, or statutory product liability.
9. Privacy and changes
See the Privacy Notice. We may update these terms prospectively when the service or law changes. Material changes will be communicated reasonably in advance; an existing paid period will not be materially reduced without an appropriate remedy.
10. Governing law and contact
German law applies, without depriving consumers of mandatory protections of their country of residence. Statutory courts have jurisdiction. Questions can be sent to info@ahura.cloud.
