Terms of Service
Last updated: November 9, 2026
These Terms govern your use of the Stiida platform (web app and AI features). By creating an account or using Stiida, you agree to these Terms. If you do not agree, please do not use the service.
Stiida is a product operated by Academial Technologies Limited.
1.Your account
You must provide accurate registration information and keep your credentials secure. You are responsible for all activity under your account. One account per person. If you are under 16, you may only use Stiida with a parent or guardian's permission.
2.Acceptable use
You agree not to upload content you have no right to share, use Stiida for unlawful purposes, bypass credit limits, rate limits or security measures, or scrape, resell or redistribute the service. We may suspend accounts that violate these rules.
3.Stiida Credits & subscriptions
Stiida Credits are a limited, non-transferable, non-refundable virtual entitlement used to access AI features. They have no cash value, cannot be exchanged for money, and reset according to your plan cycle. Subscription fees are billed in advance, monthly or yearly. You may cancel anytime; access continues until the end of the paid period. Prices and credit allocations may change with reasonable notice.
4.AI-generated content
AI outputs, including tutor answers, tests, grading and flashcards, are generated automatically and may contain errors. They are provided for study support only and are not academic, legal, medical or professional advice. You are responsible for verifying answers against your official course materials.
5.Your content
You keep ownership of everything you upload or create, including documents, recordings, notes, flashcards, tests and answers. You grant Stiida a limited licence to store, process, index and display your content solely to operate the service.
6.Our intellectual property
The Stiida platform, software, branding, prompts and credit system are made available by Academial Technologies Limited. Nothing in these Terms transfers any rights in Stiida to you. Third-party materials, including textbooks, remain the property of their respective owners.
7.Termination
You may delete your account at any time from your settings. We may suspend or terminate accounts that breach these Terms, abuse the platform or pose a security risk. After termination, your licence to use the service ends and your content is deleted under our Privacy Policy.
8.Disclaimers & limitation of liability
The service is provided "as is" and "as available", without warranties of any kind. To the maximum extent permitted by law, Stiida's total liability arising from your use of the service is limited to the amount you paid us in the 12 months before the claim.
9.Changes & contact
We may update these Terms; material changes will be announced in-app or by email. Questions? Contact us at [email protected].
10.Subscription changes
Existing access stays in place until your payment provider confirms the effective change. AI credits follow Stiida's existing 30-day policy, not your payment provider's financial proration.
11.Storage and retention
Uploaded recordings and other files are retained while your account remains active unless you delete them. Storage limits are Free 100 MB, Starter 1 GB, Pro 5 GB, and Max 10 GB. Reaching your limit prevents new uploads until you delete files or upgrade. We do not automatically delete user content based on its age. Account deletion and legal obligations are described in the Privacy Policy.
