We use your personal Information to provide our services to you, which includes: offering products for sale, processing payments, shipping and fulfillment of your order, and keeping you up to date on new products, services, and offers.

SMS/Text Messaging

By providing your phone number and opting in, you consent to receive SMS text messages from DTFonestop. Consent to receive SMS messages is not a condition of any purchase. These messages may include order updates, shipping notifications, quote follow-ups, appointment reminders, and responses to your inquiries. Message frequency varies based on your activity. Message and data rates may apply. You can opt out at any time by replying STOP to any message. Reply HELP for assistance. Your phone number and opt-in consent will not be shared with third parties for marketing purposes.

Lawful Basis

Pursuant to the General Data Protection Regulation ("GDPR"), if you are a resident of the European Economic Area ("EEA"), we process your personal information under the following lawful bases:

• Your consent;
• The performance of the contract between you and the Site;
• Compliance with our legal obligations;
• To protect your vital interests;
• To perform a task carried out in the public interest;
• For our legitimate interests, which do not override your fundamental rights and freedoms.

Retention

When you place an order through the Site, we will retain your Personal Information for our records unless and until you ask us to erase this information. For more information on your right of erasure, please see the 'Your rights' section below.

Automatic decision-making

If you are a resident of the EEA, you have the right to object to processing based solely on automated decision-making (which includes profiling), when that decision-making has a legal effect on you or otherwise significantly affects you.

We DO NOT engage in fully automated decision-making that has a legal or otherwise significant effect using customer data.

Our processor Shopify uses limited automated decision-making to prevent fraud that does not have a legal or otherwise significant effect on you. Services that include elements of automated decision-making include:

• Temporary blacklist of IP addresses associated with repeated failed transactions. This blacklist persists for a small number of hours.
• Temporary blacklist of credit cards associated with blacklisted IP addresses. This blacklist persists for a small number of days.

Your Rights

GDPR

If you are a resident of the EEA, you have the right to access the Personal Information we hold about you, to port it to a new service, and to ask that your Personal Information be corrected, updated, or erased. If you would like to exercise these rights, please contact us through the contact information above.

Your Personal Information will be initially processed in Ireland and then will be transferred outside of Europe for storage and further processing, including to Canada and the United States. For more information on how data transfers comply with the GDPR, see Shopify's GDPR Whitepaper: https://help.shopify.com/en/manual/your-account/privacy/GDPR.

CCPA / CPRA (California)

If you are a resident of California, you have the right to access the Personal Information we hold about you (also known as the 'Right to Know'), to port it to a new service, to correct it, and to ask that your Personal Information be deleted. You also have the right to opt out of the "sale" or "sharing" of your personal information and the right not to be discriminated against for exercising your rights. If you would like to exercise these rights, please contact us through the contact information above.

Do Not Sell or Share My Personal Information. We do not sell your personal information for money. However, as described in the "Behavioral Advertising" section, we "share" personal information for cross-context behavioral advertising (for example, via Shopify Audiences and our advertising partners), which is treated as "sharing" under California law. You can opt out of this sharing by: (a) using the "Do Not Sell or Share My Personal Information" link in our website footer; (b) following the opt-out instructions in the "Behavioral Advertising" section above; or (c) enabling a Global Privacy Control (GPC) signal in your browser — we treat a valid GPC signal as a request to opt out of the sale/sharing of your personal information.

If you would like to designate an authorized agent to submit these requests on your behalf, please contact us at the address above.

The length of time that a cookie remains on your computer or mobile device depends on whether it is a "persistent" or "session" cookie. Session cookies last until you stop browsing and persistent cookies last until they expire or are deleted. Most of the cookies we use are persistent and will expire between 30 minutes and two years from the date they are downloaded to your device.

You can control and manage cookies in various ways. Please keep in mind that removing or blocking cookies can negatively impact your user experience and parts of our website may no longer be fully accessible.

Most browsers automatically accept cookies, but you can choose whether or not to accept cookies through your browser controls, often found in your browser's "Tools" or "Preferences" menu. For more information on how to modify your browser settings or how to block, manage or filter cookies can be found in your browser's help file or through such sites as: https://www.allaboutcookies.org.

Because there is no consistent industry standard for legacy "Do Not Track" (DNT) browser signals, we do not respond to DNT signals. However, we do honor Global Privacy Control (GPC) signals: where required by law, we treat a valid GPC signal from your browser as a request to opt out of the sale or sharing of your personal information.

Part B — DTF OneStop Gang Sheet Builder (Shopify App) Privacy Policy

Last updated: June 13, 2026

DTF OneStop Gang Sheet Builder ("the App", "we", "us") is a Shopify application operated by DTF Onestop (Vincent Chen). The App lets a merchant's customers lay out direct-to-film (DTF) transfer artwork on a gang sheet, order it, and lets the merchant download the print-ready files. This policy explains what data the App processes and how. (This is separate from, and in addition to, the DTFonestop.com store policy in Part A above.)

1. Who this policy is for

• Merchants who install the App on their Shopify store.
• Shoppers (the merchant's customers) who use the gang sheet builder on the merchant's storefront.

Our role. For order data we access from a merchant's store, the merchant is the data controller and we act as a data processor on the merchant's behalf, processing that data only to provide the App's functionality. For our own operational data (for example, billing records), we act as a controller. The App is not directed to children under 13 and we do not knowingly collect data from them.

2. What we collect and why

From the merchant's store (via the Shopify API, with the merchant's authorization):

• Order data — order number, financial/fulfillment status, line items, and the design-file references attached to gang sheet line items. We use this to (a) calculate our usage fee (1% of gang sheet items per paid order) and (b) show the merchant their gang sheet orders so they can download files and fulfill. We do not read, store, or display customer names, email addresses, phone numbers, or shipping addresses.
• Shop session credentials — standard Shopify offline access tokens needed for the App to function.

From shoppers using the builder:

• Design files — the artwork/print files a shopper uploads or generates. Stored so the merchant can download them to fulfill the order, and (if the shopper chooses "save to cloud") so the shopper can reopen the design on another device.
• Saved-design metadata — when a shopper saves a design, we store a design name, a share code, a reference to the stored file, and (if the shopper is logged into the storefront) the shopper's opaque Shopify customer identifier. We do not store the shopper's name, email, phone, or address.
• Local browser storage — the builder uses your browser's local storage to keep an in-progress draft on your device. This stays on your device unless you choose "save to cloud."

We do not process payment/card information (handled entirely by Shopify), and within the App we do not sell or share personal data with advertisers or data brokers.

3. How we store and protect data

• Data is transmitted over encrypted connections (HTTPS/TLS).
• Application data, the database, and design-file object storage (S3-compatible) are hosted on Railway, which provides encryption at rest.
• Access is controlled by Shopify session authentication; direct file uploads and design-file access use short-lived signed tokens and unguessable file identifiers.
• We follow data minimization — we only access the order fields the App needs and we do not store customer contact or address information.

4. Third parties / sub-processors

• Shopify — the platform the App runs on (order, product, and session data).
• Railway — application hosting, database, and S3-compatible object storage for design files.

We share data with these providers only to operate the App.

5. Data retention and deletion

• Design files and saved-design metadata are retained to support cross-device reopening and reordering. A shopper can delete an individual saved design in the builder.
• Shopper data deletion (GDPR customers/redact): when Shopify notifies us that a customer requests redaction, we delete that customer's saved designs and the associated files.
• Shop data deletion (GDPR shop/redact, ~48 hours after a merchant uninstalls): we delete all data we hold for that shop — saved designs, stored files, billing state, fee logs, and sessions.
• Data access requests (customers/data_request): we hold no customer name/email/address, so there is no personal contact data to return; saved designs are keyed only by an opaque id.

6. Your rights

Depending on your region (e.g. GDPR/EEA, UK, CCPA/California), you may have rights to access, correct, or delete your personal data. Shoppers should direct requests to the merchant they ordered from; merchants and shoppers can also contact us at the address below.

7. International transfers

Data may be processed in the United States and other regions where our providers operate.

8. Changes to this policy

We may update this policy; the "Last updated" date will change accordingly.
