Membership Agreement

Last updated: 2026-09-26

This is the membership agreement for WorkMark Camera on iPhone and iPad (also known as 水印相机) — the Monthly, Quarterly and Yearly memberships sold in the iOS version — published by Beijing Baladuoduo Technology Co., Ltd. It is the agreement you accept in the app before buying a membership, and it supplements the iOS terms of service. Company-wide rules are in the Baladuoduo Privacy Policy; where the two differ, this page governs for this app.

1. Scope

This Membership Agreement is between you and the operator of WorkMark Camera (the "App") and covers your purchase and use of the App's membership. Membership is offered only in the iOS version of the App, through Apple In-App Purchase. Please read it carefully before buying; ticking the box and completing the purchase means you accept it in full. It supplements the Terms of Service and, for membership matters, prevails where the two differ.

2. What membership includes

While your membership is active you can use the members-only features, which currently are:

· Remove app mark — turn on "Remove app mark" in the camera settings and the line with the App's name is no longer stamped on the photos and videos you take.

Membership benefits are those actually provided in the App. We may add to, adjust or improve them as the business requires and will notify you appropriately.

3. Plans and billing

Membership comes in three plans — Monthly, Quarterly and Yearly — all of them auto-renewing subscriptions. The price and period of each plan are those shown on the purchase page and on the Apple App Store checkout page; prices appear in the currency and price tier of your Apple account's region.

Membership is sold through Apple In-App Purchase. Once you confirm, the charge goes to your Apple ID account; the App never receives your card or bank details.

4. Auto-renewal

Monthly, Quarterly and Yearly memberships renew automatically:

1. Unless you turn off auto-renewal at least 24 hours before the current period ends, Apple charges your account at the plan price within the 24 hours before the period ends and extends the subscription;

2. The amount charged is the price shown on the purchase or checkout page at that time; if the price changes, Apple notifies you under its own rules;

3. Renewed time is added on top of the existing expiry date.

5. Turning off auto-renewal

You can turn off auto-renewal at any time in your Apple account settings: open Settings > Apple ID (your name at the top) > Subscriptions, find this App and switch off auto-renewal.

Your benefits for the current period are unaffected; after it ends nothing further is charged. Note that cancelling within 24 hours of the renewal date may not stop that renewal, so act early.

6. Refunds

Membership purchases are collected by Apple, and refunds follow Apple App Store rules. To request one, go to reportaproblem.apple.com; Apple reviews it under its own policy. When you request a refund, Apple may require us to supply limited information about the transaction (such as how long the account has existed, purchase and refund history and whether benefits were delivered) to help Apple assess it. That information is used only for the refund assessment.

7. When benefits start and end

Benefits begin once your purchase completes and passes verification. If a subscription expires without renewal, benefits end on the expiry date and you return to the free tier: members-only features stop working (for example, Remove app mark switches off and new photos and videos carry the App's name again), while the App's free features are unaffected. If a purchase is fully refunded or revoked, the corresponding benefits are withdrawn.

8. Minors

If you are a minor, please buy a membership only with a guardian's consent and guidance. A guardian who finds that a minor purchased without consent can request a refund through Apple and can contact us via Send feedback in the App.

9. Changes to this agreement

We may revise this agreement and will publish the revision in the App. Revised terms take effect when published. Continuing to buy or use membership after that means you accept them.

10. Contact us

If you have questions, comments or complaints about this agreement or about membership, use Send feedback in the App or email service@baladuoduo.com. We will respond as soon as we can.
