Posso Grade Booster – Terms of Use

1. The service

Posso Grade Booster ("Posso") is a study app by Digination Oy (business ID 1548182-0) that uses AI to make quizzes from study material the user scans. By using Posso you accept these terms. A guardian must accept the terms for a user under 13.

2. Account

You sign in to Posso with your Apple ID or with a code sent to your email. A user under 13 can use a guardian's email address. The account is personal. You can delete it at any time in Settings; the deletion takes effect after 24 hours.

3. Subscriptions and purchases

• Subscriptions (monthly or yearly) and one-time purchases are paid through Apple, and Apple's terms apply to them. A subscription renews automatically until you cancel it in your Apple ID settings at least 24 hours before the end of the period.
• The free 7-day trial can be used once. Unless you cancel it, it turns into a paid subscription.
• The monthly quotas of a subscription (pages and the teacher's energy) start over at the beginning of each calendar month; unused ones do not carry over. Purchased extra pages never expire and can be used while a subscription is active.
• Pages are counted by content: one page is up to about 350 words of study material (about 100 words in word lists).
• A subscription is personal and cannot be used on more than one Posso account.
• Refunds are handled by Apple (reportaproblem.apple.com), unless stated otherwise below.

Changes to quotas. The AI used in Posso costs us for every scanned page and every check. If the prices of the AI service or other costs of providing the service rise significantly, we may reduce the quotas of subscriptions (pages or the teacher's energy) or change how pages are counted.

• We will tell you about the change in the app at least 30 days before it takes effect.
• Monthly subscription: the change takes effect at the earliest from the start of the billing period after the notice. You can cancel the subscription before then, and the new period is not charged.
• Yearly subscription: the quotas stay the same until the end of the year you have paid for. If the change is nevertheless necessary to keep the service running before then, you can choose to continue with the smaller quotas or end the subscription. If you end it, we refund the share of the price for the unused time. Ask for the refund at info@posso.mobi; we pay it ourselves, because Apple does not handle partial refunds like this.
• The change does not affect extra pages you have already bought.
• Price increases are made through Apple and need your approval under Apple's rules.

4. Acceptable use

Use Posso only for your own studies. Do not scan material you have no right to use, personal data or other inappropriate content. Overloading the service or getting around the quotas is not allowed. We may limit use or close an account if these terms are broken.

5. Content and AI

• The rights to the material you scan stay with their owners. You give us the right to process the material to make your quiz.
• Quizzes, answers and the checking of your answers are made by AI and may be wrong or incomplete. The AI may, for example, misread a photo, word a question misleadingly, give a wrong correct answer or assess your answer wrongly.
• We are not responsible for the questions, answers or feedback being correct. You must check the facts yourself from your study material or with your teacher. Posso is a practice aid; it does not replace your study material and does not guarantee test results.

6. Processing outside the EU

• Scanned photos and the answers you type are sent for processing to an AI service (Anthropic, United States), that is outside the EU and EEA. The transfer is based on the European Commission's standard contractual clauses, and Anthropic does not use the data to train its models. See the privacy policy for details.
• Do not scan or type sensitive or private information, such as health information, personal identity numbers, contact details, passwords, photos of people or other people's personal data. Scan study material only.

7. Limitation of liability

The service is provided as is. We aim to keep it running, but there may be interruptions. We are not liable for damage caused by errors in content produced by AI. To the extent permitted by mandatory law, our liability is limited to the amount paid for the service in the last 12 months.

8. Changes and ending the service

We may change these terms or the service; we will tell you about significant changes in the app. If we end the service, we will tell you at least 30 days in advance and refund the share of a yearly subscription for the unused time.

9. Governing law

These terms are governed by Finnish law. As a consumer you may take a dispute to the Finnish Consumer Disputes Board (kuluttajariita.fi) or use the EU online dispute resolution platform.
