Terms of Service

Last updated: 28 August 2026

These terms govern use of FastOG, including fastog.com, the image-generation API, and the FastOG app for Shopify. By creating an account or installing the app you agree to them. If you are agreeing on behalf of a company, you confirm you are authorised to do so.

FastOG is operated by the owner of fastog.com ("we", "us"). Contact: [email protected].

1. What the service is

FastOG generates Open Graph images — the preview picture social networks display for a shared link — from templates you configure, and serves them at signed URLs.

2. Your account

Keep your credentials and API keys secret. You are responsible for everything done with them, including usage and charges. Tell us promptly at [email protected] if you believe a key has been exposed, and we will help you rotate it.

3. Plans, billing and quotas

Paid plans are billed monthly in advance. Each plan includes a monthly allowance of generated images; identical requests are cached and are not counted again.

• Shopify installations are billed by Shopify under its own billing terms. Upgrades, downgrades and proration are handled by Shopify, and cancellation is done in your Shopify admin.
• Direct subscriptions are billed by our payment processor and renew automatically until cancelled.
• We may change prices with at least 30 days' notice. Continuing to use the service after a price change takes effect constitutes acceptance.
• Unused allowance does not roll over and has no cash value.

4. Refunds

Fees are non-refundable except where the law requires otherwise. Specifically:

• We do not refund partial billing periods when you cancel. Cancellation stops future renewals; access continues to the end of the paid period.
• We do not refund an allowance you did not use.
• We do not refund charges arising from your own configuration — for example covers generated with the wrong template, wording or colours, or requests made by your own integration.
• Where a Shopify plan was purchased, any refund is at Shopify's discretion and subject to Shopify's terms, not ours.
• If we fail to deliver the service for a sustained period due to our own fault, contact us and we will consider a pro-rata credit toward future use. Service credits are the only remedy we offer for unavailability.

5. Acceptable use

You may not use FastOG to generate or distribute material that is unlawful; that infringes another party's intellectual property or privacy; that is deceptive; or that impersonates a person or organisation. You may not attempt to bypass quotas or signing, probe or overload the infrastructure, or resell raw image generation as a competing service without our written agreement.

We may suspend an account that breaches this section, and will tell you why where we lawfully can.

6. Your content

You keep all rights in the text, images, brand assets and store data you supply, and in the covers generated from them. You grant us only the licence needed to operate the service: to store, process, cache and serve that material in order to generate and deliver your images.

You confirm you have the rights to whatever you supply. You are responsible for the content of your covers.

7. Availability and changes

We aim for continuous availability but do not guarantee it. We may perform maintenance, change or withdraw features, and change template designs. We will avoid changes that break existing signed URLs where reasonably practicable, and will give notice of material breaking changes where we can.

Generated images are served through a cache. A change you make may take time to appear for a link already scraped by a social network, because those networks cache previews independently and we do not control them.

8. Third-party platforms

FastOG depends on services we do not control, including Shopify, social networks, our AI model provider, and content-delivery infrastructure. We are not responsible for their outages, policy changes, or decisions — including whether a network chooses to display your cover. Nothing here makes us a partner or agent of Shopify, and Shopify is not a party to these terms.

9. Disclaimer

The service is provided "as is" and "as available". To the fullest extent permitted by law we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty that the service will be uninterrupted, error-free, or will produce any particular commercial result. We make no promise about clicks, traffic, conversion, or search ranking.

10. Limitation of liability

To the fullest extent permitted by law:

• Neither party is liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, goodwill or data, however caused.
• Our total aggregate liability arising out of or relating to the service is limited to the greater of the fees you paid us in the three months immediately before the event giving rise to the claim, or fifty US dollars (US$50).
• Nothing in these terms excludes liability that cannot lawfully be excluded, including for fraud, or for death or personal injury caused by negligence.

11. Indemnity

You will indemnify and hold us harmless against third-party claims, damages and reasonable legal costs arising from your use of the service in breach of these terms, or from content you supplied or generated through it.

12. Suspension and termination

You may cancel at any time. We may suspend or terminate access for breach of these terms, for non-payment, or where required by law. On termination your data is deleted in line with the retention periods in our Privacy Policy.

13. Changes to these terms

We may update these terms. Material changes will be announced in the app or by email at least 30 days before taking effect, except where a change is needed sooner for legal or security reasons. Continued use after a change takes effect constitutes acceptance.

14. Governing law

These terms are governed by the laws of Portugal, and the courts of Portugal have exclusive jurisdiction, without prejudice to any mandatory consumer protections available to you where you live.

15. General

If any provision is unenforceable, the rest remains in force. Our failure to enforce a provision is not a waiver of it. You may not assign these terms without our consent; we may assign them in connection with a merger, acquisition or sale of assets. These terms and the Privacy Policy are the entire agreement between us regarding the service.
