Terms of Service

for the Showio - Catalog & Line Sheet Shopify app
Last updated: 7 November 2026

These terms govern your use of the Shopify app Showio - Catalog & Line Sheet ("the App"), provided by Marius Šiupšinskas, a natural person carrying out individual activity (individuali veikla) registered in Lithuania (European Union), trading as EpicPilot Labs ("EpicPilot Labs", "we", "us"). By installing or using the App, you agree to these terms.

1. What the App does

The App reads the products in your Shopify store and turns the ones you choose into PDF files: line sheets, catalogs and price lists, with a cover and the details you choose to print. Depending on your plan, it can also update them every night when your products change, make an email-size version, and give each catalog a share link (on the Free plan, one is on at a time) that opens a page with its latest complete PDFs. The App only reads your store; it changes nothing in it and takes no orders.

2. Your responsibilities

• Your content. You are responsible for what goes into your catalogs: your product data, photos, logo, texts, prices, contact details and ordering terms. You confirm that you have the right to use them, including any third party's photos, trademarks or texts, and that anyone whose name or contact details you publish in a catalog's contact block has agreed to it.
• Your prices and offers. Wholesale prices in a PDF are worked out from the settings you choose (a percentage off retail, or a Shopify B2B catalog's prices, in that catalog's currency) and from your store's data at the time of the build. Check a PDF before you send it. What you offer your buyers, at what price and on what terms, is between you and them; we are not a party to it. What the PDF says about VAT or tax follows your settings, and its stock marks show your stock at the time of the build.
• Your share links. Anyone who has a catalog's share link can open it and download its PDFs, wholesale prices included, without signing in. You choose who gets it. If a link reaches someone who shouldn't have it, use New link or Turn off link in the App: that link stops showing your catalog at once. After you make a new link, the old one shows your store's name or logo and the catalog's contact email for up to 30 days, so buyers can ask you for the new one.
• You are responsible for complying with Shopify's terms when you use the App.
• You must not use the App unlawfully or to publish content that infringes others' rights, and you must not disrupt, overload or reverse-engineer the App, or gain unauthorised access to it.

3. The App is provided "as is"

The App is provided on an "as is" and "as available" basis, without warranties of any kind, express or implied, including any implied warranties of merchantability, fitness for a particular purpose or non-infringement.

We do not warrant that the App will be uninterrupted or error-free, that every build will succeed or finish at a particular time, or that a PDF will look the same in every viewer or on every printer.

4. No service level guarantee

Building and serving your PDFs depends on services outside our control, including Shopify's data and image services, our hosting providers and general internet connectivity. Any of these may fail, be delayed, limit traffic or change their terms. When a photo can't be fetched, the PDF shows a placeholder instead and the App marks the PDF as incomplete; share links keep serving the last complete PDF.

The App is a convenience, not a system of record. Your Shopify admin remains the authoritative source for your products, prices and stock. A PDF shows them as they were when it was built; one you downloaded or sent earlier doesn't change when your store does.

5. Plans, limits and charges

The App has a free plan and paid plans. The plans, their prices, their limits and what each includes are shown on the App's Shopify App Store listing and in the App.

Limits. Each plan includes a number of catalogs you can keep at a time; products and pages don't count toward that number, and a hand-picked list of products holds up to 500. If you have more catalogs than your plan includes, for example after moving to a smaller plan, none are deleted. All stay downloadable (on the Free plan, subject to the 60 days below). Until you are within your plan's limit again, you can't add catalogs and the ones past the limit aren't rebuilt. On a paid plan, nightly updates also pause for all your catalogs. On the Free plan, each catalog can be rebuilt at most once every 10 minutes, except while you set up a new catalog (its first 30 minutes). We may also limit how often an action can be used, or hold builds for a while for a store whose use puts an unusual load on our systems or on third-party services.

The Free plan. PDFs made on the Free plan carry a small "Made with Showio" line at the foot of each page, linked to our website; it is never placed over your products. The Free plan includes one share link at a time, and its page carries the same line. While your store is on the Free plan, its PDFs are deleted after 60 days without use: your visits to the App, rebuilds and downloads count, and so do downloads through your share link. Shopify development stores, which are for testing, are not affected. Your catalogs, their settings and their share links stay, and Rebuild now makes the PDF again for any catalog within your plan's limit.

Charges. Shopify bills paid plans with your Shopify bill. Paid plans may start with a free trial, as shown when you choose them. You are never charged without approving a plan in Shopify. Billing cycles, renewals, proration, credits and the date a plan change or cancellation takes effect all follow Shopify's billing for apps; we don't set separate rules for them. You can change or cancel your plan at any time from the App or your Shopify admin, and you may uninstall the App at any time.

Changes to plans. We may change the plans, including their prices, limits and features. We will give you at least 30 days' notice, in the App or by email, before a change that affects your store takes effect. A change that only adds to what your store gets, such as a higher limit or a new feature, may take effect at once.

6. Your content and our App

Your content stays yours. You give us the right to store, process and display it only as needed to run the App for you: to build your PDFs, keep them, and serve them to you and to the people you share them with. The PDFs the App makes for you are yours to use, print and share as you like.

The App itself, its templates and its design remain ours. The fonts embedded in your PDFs, Spectral and Barlow, are used under the SIL Open Font License.

6a. Personal data in your catalogs

Your catalogs may contain personal data, for example a sales contact's name, email and phone number in the contact block, or a person named in a product description. For that data you are the controller and we are your processor, and this section is our agreement under Article 28 of the GDPR:

• we process it only to build, store and serve your catalogs as you set them up in the App, which are your documented instructions, and for nothing else;
• only the App's operator can access it, and keeps it confidential;
• we use the service providers listed in section 8 of our Privacy Policy as subprocessors, under data protection terms that bind them in the same way; we will tell you in advance, in the App or by email, before we add or replace one, and you can object by uninstalling the App before the change takes effect;
• we keep it secure as section 12 of our Privacy Policy describes, and tell you without undue delay if a personal data breach affects it;
• we help you, as far as the App's role allows, to answer requests from the people concerned and to meet your other obligations under Articles 32 to 36 of the GDPR; you can change or delete the data in the App at any time;
• we delete it with your store's other data after you uninstall the App (section 9 of our Privacy Policy), or earlier when you delete it;
• on request by email, we give you the information you need to check that we meet this section.

The App puts personal data only where you write it; you are responsible for having the right to publish it (section 2).

7. Changes to the App and discontinuation

We may add, change or remove features as the App changes. We aim to give notice of material changes that affect how you use it. Changes to what a paid plan includes follow section 5, with at least 30 days' notice before a change that affects your store.

We may discontinue the App, in whole or in part. If we do, we will give merchants reasonable advance notice, normally at least 30 days, in the App or by email, so you can download your PDFs and arrange an alternative. If we discontinue the App, we will cancel any paid plan in Shopify so that no further charges are made after the App stops working, and refund the unused part of a yearly plan paid in advance. On discontinuation or uninstall, your data is deleted as described in our Privacy Policy.

8. Limitation of liability

To the maximum extent permitted by applicable law, EpicPilot Labs shall not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, sales, data, business or goodwill, arising out of or in connection with your use of, or inability to use, the App, including a wrong, outdated, incomplete or unavailable PDF, or a share link opened by someone you didn't intend it for.

To the maximum extent permitted by applicable law, our total liability arising out of or relating to the App shall not exceed the amount you paid for the App in the 12 months before the event giving rise to the claim (zero if you paid nothing in that time).

Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by negligence, or for fraud.

9. Third-party services

The App relies on third-party services, including Shopify, each governed by its own terms and privacy practices. We are not responsible for those services, their availability or any changes they make. Showio - Catalog & Line Sheet is not affiliated with, endorsed by, or sponsored by Shopify.

10. Privacy

How we handle data is described in our Privacy Policy, which forms part of these terms.

11. Termination

You may stop using the App at any time by uninstalling it from your Shopify store. We may suspend or end your access, or turn off a share link, if you breach these terms, or if Shopify, the law or the protection of the App and other merchants requires it.

12. Changes to these terms

We may update these terms as the App changes or as legal requirements change. We will give at least 30 days' notice, in the App or by email, before a change that affects your rights or what you pay takes effect. The "Last updated" date at the top shows the latest revision. If you don't agree to a change, you can change your plan or uninstall the App before it takes effect; using the App after that means you accept the updated terms.

13. Governing law

These terms are governed by the laws of the Republic of Lithuania. Where you are a consumer, this does not deprive you of the protection of mandatory provisions of the law of your country of residence.
