Terms of Service

Last updated: 2026-05-03

By purchasing or using Cullstack, you agree to these terms. They are written in plain language because we want you to actually read them. If anything is unclear, email legal@aviastone.com.

1. License grant

A Cullstack license grants you a non-exclusive, non-transferable right to install and use Cullstack on up to three (3) devices that you own or control, for personal or commercial purposes. The license is perpetual for the major version you purchased (e.g. Cullstack 1.x).

2. Refunds

We offer full refunds within 14 days of purchase, no questions asked. Email sales@aviastone.com with your license key and we'll process the refund the same business day.

3. Updates

All updates within the v1.x series are included in your license. A future major version may be offered as a paid upgrade. Your v1.x license will continue to function regardless.

4. Restrictions

You may not redistribute, resell, sublicense, or reverse-engineer Cullstack. You may not remove license-validation mechanisms or use Cullstack in ways that violate applicable law. Studio / volume licensing is available — contact sales@aviastone.com.

5. No warranty

Cullstack is provided "as is", without warranty of any kind, express or implied, including but not limited to fitness for a particular purpose. While we work hard to make Cullstack stable and reliable — particularly with large libraries — you are responsible for maintaining your own photo backups.

6. Limitation of liability

To the fullest extent permitted by law, Aviastone LLC's total liability arising from your use of Cullstack is limited to the amount you paid for your license. We are not liable for any loss of data, lost photos, or consequential damages.

7. Changes to these terms

We may update these terms occasionally. Material changes will be posted on this page and emailed to active licensees. Continued use of Cullstack after notice constitutes acceptance.

8. Governing law

These terms are governed by the laws of the State of Delaware, United States. Disputes will be resolved through binding arbitration in Delaware, except where applicable consumer protection law provides for local jurisdiction.
