2. Beta Disclaimer

5. Ownership of Uploaded Data

The user owns all uploaded data. Canvastera retains the right to display the data and delete it when necessary.

6. Prohibited Content

Users are strictly prohibited from uploading, sharing, or creating any harmful, offensive, or illegal content, including but not limited to harmful images or text. Canvastera reserves the right to remove any content that violates this provision and take appropriate action against the user.

9. Cancellation and Termination

Cancellation by You:

You can cancel your Canvastera account at any time by contacting our support team at support@canvastera.com.

  • If you cancel before the end of your current billing period, your cancellation will take effect at the end of that period. You will not be charged again.

Termination by Canvastera:

We reserve the right to suspend or terminate your account and refuse service for any reason at any time. This may include account deactivation, deletion of your data, and barring future use of the service.

  • Reasons for termination may include, but are not limited to, violation of our terms of service or abusive behavior towards our customers, employees, or officers.

11. Contact Information

If you have any questions or concerns about these Terms of Use, please contact us at support@canvastera.com.

12. Creation and content retention

All users can create unlimited posters and communities with unlimited members and basic community management. The full multimedia editor is available to everyone, except AI features.

The following retention policy is planned. Retention enforcement is not active yet. We will announce the effective date before the policy starts.

  • Free: Each poster receives an 18-month retention period from its creation date. Editing or viewing a poster does not reset this period.
  • Single: Personal posters remain stored while the subscription is active. After expiration, covered posters receive an additional 18-month retention period. Renewal before deletion preserves them under the active subscription.
  • Group: Posters created within a Group by any user remain stored while the Group subscription is active. After expiration, covered content receives an additional retention period of up to 18 months, unless institutional agreements or applicable legal requirements specify otherwise.
  • Personal posters belonging to Admins, Group Mentors, and Members follow their own Free or Single retention policies.
  • All beta-period posters receive a fresh 18-month retention period from the effective date of the updated policy.

We will notify users before scheduled permanent deletion, with an opportunity to preserve content or renew an eligible subscription. After the applicable retention period, posters and associated stored media may be permanently deleted.

Group development

Group features are currently in development. Purchasing a Group subscription supports the development of classroom and organization management capabilities. The planned management capabilities are not yet available.

One Group subscription will support multiple Groups, such as schools, and multiple Communities within each Group. Group subscriptions will support unlimited Viewers without licensed seats. Viewers can see content permitted by Group and Community settings, but cannot create or edit Group posters. Users with a role other than Viewer can create posters within a Group under its subscription plan. Private Group posters remain visible to authorized Admins. Students can create private posters in a Group or Group Community; these remain visible to authorized Admins and Group Mentors assigned to that Group. Community visibility allows other users and Students to see shared content, as permitted by Community and Group settings. Any user except a Student can create personal private posters outside the Group under their own Free or Single plan. Only the creator can see those personal private posters.

13. Payments, refunds, upgrading and downgrading terms

Payment:

  • We do not store your credit card information and do not sell your data.
  • Prepaid Plan: Paid plans require prepayment to maintain service of billing period you choose (monthly / yearly).
  • If payment is not received, your account will transition to Free. Paid publishing and privacy features require an eligible active subscription. See Section 12 for the planned retention policy.
  • Retention enforcement is not active yet. Your payment supports continued development. Paid password protection and website embedding require an eligible active subscription.

Billing:

  • Paying customers are automatically billed via credit card or PayPal (depending on your preference during checkout with Paddle.com).

Account Management:

  • You can upgrade or downgrade your plan (to paid or Free Account Model) at any time within your account settings or by contacting support at support@canvastera.com.
  • Downgrading may cause feature loss and potential data loss for exceeding users (who will transition to the Free Account Model). We are not liable for such data loss.

Payment Processing:

  • Paddle.com handles all payment processing, customer service inquiries, and returns.
  • Fees are inclusive of all taxes. Paddle collects and remits taxes to the relevant authorities. See Paddle's Terms of Use for details.
  • Fees are non-refundable.

Refunds

  • We offer 48-hours refund period for your Paid Plan if your account / group users has no posters created.
  • Canvastera has no liability to you, nor any obligation to provide a refund to you, in connection with internet or other Canvastera Service outages or failures that are caused by the actions of government authorities, other third parties, or events beyond our control.
  • Contact us at support@canvastera.com

14. Modifications to the service and prices

We reserve the right to modify or discontinue any part of the service, temporarily or permanently, with or without notice.

  • We strive to exempt existing customers from price changes. However, we may occasionally adjust pricing and will provide at least 30 days' notice via email, blog post, or changelog update.
  • Canvastera is not liable for any service modifications, price changes, suspensions, or discontinuations.
  • If you have prepaid fees directly to Canvastera for a Paid Plan that Canvastera permanently discontinues prior to the end of your Prepaid Period (as that term is defined in the "Payments" section above), Canvastera will refund you the prorated portion of the prepaid fees for the Prepaid Period after such discontinuation. Your account and billing information must be up to date in order for us to refund you.

15. Fair use of uploads and storage

This policy applies to all accounts, including Free, Single, and Group subscriptions. Uploaded media and attachments must support the creation, presentation, or sharing of Canvastera posters. You may upload material while preparing a poster; it does not need to appear in a finished or public poster immediately.

Unlimited posters and communities do not include unlimited uploaded storage. This fair-use policy does not set a fixed total storage allowance in gigabytes (GB). Any separate total storage allowance or individual file upload limit must be published for your plan or agreed with you before it applies. A paid subscription does not exempt an account from these limits or this fair-use policy.

You must not use poster media or attachments as general file storage, a backup service, or a file distribution service unrelated to poster use. Examples of abuse include storing large collections of unrelated files, creating posters only to hold such files, or using repeated uploads or multiple accounts to bypass storage limits. Legitimate poster drafts and supporting classroom or project materials are permitted within the applicable limits. We assess storage abuse by its connection to genuine poster work, the nature and volume of uploaded files, attempts to bypass limits, and the effect on the service. High storage use alone does not establish abuse.

If an account exceeds its applicable storage allowance or violates this policy, we may restrict further uploads and ask the account holder to reduce storage use or remove unrelated files. Continued or serious abuse may result in account suspension or termination, including for paid accounts. Where practicable, we will give advance notice and an opportunity to correct the issue. We may act immediately if necessary to protect the service or prevent ongoing abuse. We will explain the reason for any restriction and how to contact us to request a review at support@canvastera.com.

By using Canvastera, you agree to abide by these terms and conditions. Thank you for being a part of our beta testing community!
