5.4 — Third-Party Infrastructure

You acknowledge that Opensolr uses third-party vendors and hosting partners (including, but not limited to, AWS and Hetzner AG) to provide the hardware, software, networking, storage, and related technology required to operate the Service. Opensolr is not liable for outages, interruptions, or performance degradation caused by these third-party providers.

Except as expressly stated in Section 5.2, the Service is provided on an "as is" and "as available" basis. Opensolr does not warrant that:

1. the Service will meet your specific requirements;
2. the Service will be uninterrupted, timely, or error-free;
3. the results obtained from the use of the Service will be accurate or reliable; or
4. any defects in the Service will be corrected within a particular timeframe.

6 Acceptable Use Policy

You agree not to use the Service to:

1. engage in any activity that is illegal or unauthorised under applicable law, including but not limited to copyright, trademark, or data protection laws;

3. upload, transmit, or distribute any viruses, worms, malware, or other code of a destructive or disruptive nature;
4. send, facilitate, or enable unsolicited bulk communications (spam) of any kind;
5. attempt to gain unauthorised access to the Service, other users' accounts, or any systems or networks connected to the Service;
6. interfere with or disrupt the integrity or performance of the Service, including through excessive API requests that degrade service for other users;
7. reproduce, duplicate, copy, sell, resell, or exploit any portion of the Service without express written permission from Opensolr; or

6.2  If your resource usage (bandwidth, CPU, disk I/O, or API requests) significantly exceeds the limits of your plan or causes degradation for other users, Opensolr reserves the right to throttle, suspend, or require an upgrade of your Account, with reasonable notice where practicable.

6.3  Violation of this Acceptable Use Policy may result in suspension or termination of your Account in accordance with Section 9.

7 Payment, Billing, and Subscriptions

7.1 — Free Trial

New users may register for a free trial Account. No credit card is required. Free trial Accounts are subject to resource limits as published on the Pricing Page and carry no uptime or support guarantees.

7.2 — Paid Subscriptions

Upon subscribing to a paid plan, or at the conclusion of your free trial (if applicable), you will be billed for the upcoming period of service at the rate displayed at the time of purchase.

7.3 — Payment Processing

All payments are processed through Stripe, our authorised payment processor, unless otherwise agreed in a separate MSA. No payment card numbers or financial credentials are stored on Opensolr servers.

7.4 — Upgrades and Downgrades

You may upgrade or downgrade your plan at any time through the Pricing Page. All changes are pro-rated: you are charged or credited only for the difference based on the unused portion of your current billing period. Changes take effect within five to ten (5–10) minutes.

When you downgrade to a lower plan, the features, resource limits, and support level of that lower plan apply immediately.

7.5 — Taxes

All fees are exclusive of applicable taxes, levies, or duties imposed by taxing authorities. You are responsible for the payment of all such taxes, except where Opensolr is legally required to collect and remit them on your behalf.

7.6 — Renewal and Late Payment

Subscriptions renew automatically at the end of each billing period. Opensolr will attempt to charge your payment method on file and will send a notification if payment fails.

7.7 — Yearly Subscriptions

If you are on a yearly subscription, you must notify Opensolr of your intention to cancel at least thirty (30) calendar days before the subscription renewal date. Failure to provide timely cancellation notice will result in automatic renewal for a subsequent annual term.

8 Refunds and Chargebacks

8.1  Refunds are available for new accounts only (no prior paid orders) and only within the first ten (10) days of the initial paid subscription.

8.2  Outside of the refund window described in Section 8.1, all purchases are final. When you cancel a subscription, unused days are converted to account credit that may be applied toward future upgrades or renewals.

8.3  If you believe a charge is incorrect, please contact support@opensolr.com before initiating a chargeback with your bank or payment provider. Resolving billing disputes directly allows for faster resolution and avoids complications that may delay any applicable refund.

9 Cancellation, Termination, and Suspension

9.1 — Cancellation by You

You may cancel your subscription at any time through the Opensolr Control Panel under Billing, or by contacting help@opensolr.com. Cancellation takes effect immediately. You will not be charged for subsequent billing periods. Unused days are converted to account credit in accordance with Section 8.2.

9.2 — Free Trial Accounts

Free trial Accounts carry no service guarantee. Opensolr reserves the right to remove indexes, configurations, and data associated with inactive free trial Accounts — defined as Accounts where none of the following has occurred for more than thirty (30) consecutive days:

1. logging into your Opensolr Account;
2. inserting, updating, or deleting data in an index;
3. modifying index configuration files; or
4. performing search or API requests against an index.

9.3 — Termination or Suspension by Opensolr

Opensolr may suspend or terminate your Account if:

1. you breach any provision of these Terms, including the Acceptable Use Policy (Section 6);
2. your Account has an overdue balance beyond the grace period described in Section 7.6;
3. continued provision of the Service to you would, in our reasonable judgment, pose a security risk or cause harm to other users or to the platform; or
4. we are required to do so by law or by order of a court or regulatory authority.

Where practicable, Opensolr will provide notice and a reasonable opportunity to cure the breach before termination. In cases of severe or repeated violations, immediate termination without prior notice may apply.

9.4 — Effect of Termination

Upon termination, your right to access and use the Service ceases immediately. Opensolr may delete all Content associated with your Account after a reasonable retention period (not exceeding thirty days from termination), unless a longer retention period is required by law or by a separate agreement.
