Privacy Policy

01Who we are

The app “Watermark remover, Logo eraser” (the App) is developed and published by Chengmai Qingzhou Xinghe Network Technology Co., Ltd. (澄迈轻舟星河网络科技有限公司, “we”, “us”), under the SailingLab brand. We are responsible for the processing of personal information described in this policy.

Questions? E-mail sailinggalaxytech@gmail.com.

02Summary

• The App does not require an account and does not ask for your name, phone number or e-mail address.
• We use Google Firebase to understand how the App is used and to configure it remotely.
• The free version shows ads. Our ad partners use your device’s advertising ID and similar data to show and measure ads, and — where required — only after you give consent.
• Purchases are processed by Google Play. We never receive your card details.

03Information we process

Media you choose to edit

When you select a video or image, the App reads it from your device to edit it and saves the result back to your device. This happens locally; the files are not sent to us.

Video links you paste (download feature)

If you use the in-app download feature and paste a link to a public video, that link is sent to a third-party link-parsing service (accessed through RapidAPI) to retrieve the downloadable video address, and the video is then downloaded directly to your device. Only the link you paste is sent — no other personal information.

Usage and device information

Through Google Firebase Analytics we collect pseudonymous usage information such as: which features you use (e.g. compress, remove watermark), whether you open the subscription screen or start a purchase, ad impressions, app version, device model, operating system version, language, approximate location derived from your IP address (country/region level), and app-instance identifiers.

Advertising data

In the free version, our ad mediation partner and the ad networks listed below may collect your device’s advertising ID, IP address, device and network information, and information about ad interactions (such as views and clicks) to deliver, measure and — where you have consented — personalize ads.

Purchase information

When you buy a subscription or lifetime upgrade, Google Play processes the payment. We receive limited purchase information from Google Play — such as the product purchased, order number, purchase time, purchase token and subscription status — so we can unlock Premium and handle refunds. We do not receive your name, card number or billing address.

Support messages

If you e-mail us, we receive your e-mail address and whatever you choose to include (for example, an order number or screenshots). We use it only to answer you.

Other installed apps

The App may check whether one specific SailingLab app (InSave) is already installed, so that we do not promote an app you already have. The App does not scan or collect a list of your installed apps.

04App permissions

You can change permissions at any time in your device’s system settings.

05How we use information

• To provide the App — editing, exporting and downloading, unlocking Premium after a purchase.
• To improve the App — understanding which features are used and where problems occur.
• To show ads in the free version and measure their performance.
• To support you — replying to messages and handling refunds.
• To keep the App secure and comply with legal obligations.

Where the EU/UK GDPR applies, we rely on: performance of a contract (providing the App and Premium features), our legitimate interests (analytics, security and improving the App), and your consent (personalized ads, where required). You may withdraw consent at any time.

06Third-party services

We share information only with service providers that help us run the App. Each processes data under its own privacy policy:

We may also disclose information if required by law, to protect our rights or users’ safety, or as part of a merger or acquisition, in which case this policy will continue to apply.

07Ads and your choices

• Consent. In the European Economic Area, the United Kingdom and Switzerland, the App asks for your consent through Google’s consent tool before personalized ads are shown.
• Advertising ID. You can reset or delete your advertising ID, or opt out of personalized ads, in your device settings (Settings → Privacy → Ads on most Android devices).
• Remove ads. Premium users do not see ads.

08Retention and security

Media you edit stays on your device and is removed when you delete it or uninstall the App. Analytics data is kept in pseudonymous form for no longer than 14 months. Support e-mails are kept as long as needed to resolve your request and meet legal obligations. Purchase records are kept by Google Play according to its policies.

Data sent by the App to our service providers is encrypted in transit. No method of transmission or storage is 100% secure, but we take reasonable measures to protect your information.

09International transfers

Our service providers may process information in countries other than your own, including the United States, Singapore and China. Where required, these transfers are protected by appropriate safeguards such as standard contractual clauses.

10Your rights

Depending on where you live — for example under the EU/UK GDPR, California privacy laws, or Korea’s Personal Information Protection Act — you may have the right to access, correct or delete your personal information, to object to or restrict certain processing, to withdraw consent, and to lodge a complaint with your local data protection authority.

Because the App has no accounts, most data is linked only to pseudonymous identifiers. To make a request, e-mail sailinggalaxytech@gmail.com; we will respond within the time required by law. You can also reset your advertising ID or uninstall the App at any time.

11Children

The App is not directed to children under 13 (or the minimum age in your country). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

12Changes to this policy

We may update this policy when the App or the law changes. We will post the new version on this page and update the date at the top. Significant changes will also be announced in the App where appropriate.
