1. Data Responsibility
Every effort is made to safeguard and back up data stored on our web host. However, Transum Mathematics is not liable for any loss of data. Users are encouraged to maintain independent backups of any important data they enter into the platform.

2. Application Availability and Support
The platform is provided on an "as is" basis, with no guarantees regarding performance or compatibility. While we strive to maintain access around the clock, technical issues or hosting disruptions may cause the application to become temporarily unavailable without notice.

3. Security of Data
Although we implement reasonable measures to protect user data, we cannot guarantee its absolute security. Users are encouraged to use pseudonyms or student nicknames in place of real names and delete data once it is no longer needed. Data will be automatically deleted after a standard retention period (currently two years).

4. Subscription Cancellation Policy
Subscriptions are sold on an annual basis and cannot be cancelled mid-term. At the end of the subscription period, the subscription will expire unless payment or a purchase order has been received to renew it for the following year.

5. Refunds for Discontinued Service
In the unlikely event that Transum Mathematics ceases operations, users will receive a prorated refund based on the unused portion of their current subscription.

6. Renewals and Expiry
Subscriptions are valid for one year from the date of activation. If no renewal payment or purchase order is received by the end of the subscription period, the subscription will automatically expire.

7. Limitation of Liability
Transum Mathematics is not responsible for any indirect, incidental, or consequential damages arising from the use or inability to use the platform.

8. Changes to Terms and Conditions
Transum Mathematics reserves the right to update these terms and conditions at any time. Subscribers will be notified of any significant changes via email or through a notice on the website. Continued use of the service after changes are made constitutes acceptance of the revised terms.
