1. Introduction
Bulk Watermark is an iPhone app that adds watermarks to many photos at once. BulkWatermark team (“we”, “us”) publishes it. This policy covers the app and this website, bulkwatermark.app. It says what the app does with your data, what we collect, who helps us run the service, and what you can choose.
The short version: your photos never leave your device, and we collect only a small amount of anonymous usage data.
2. Your photos stay on your device
- Bulk Watermark asks for access to your photo library so you can pick photos and save the finished ones. You can give it limited access to selected photos only. Saving the results works without full access.
- Adding watermarks, cropping and exporting all happen on your device. Your photos, and the watermarked copies, are never uploaded to us or to anyone else.
- Background removal for image watermarks uses Apple’s Vision framework on your device. Nothing is sent anywhere.
- The app can download a catalog of watermark artwork (stickers and shapes) that we host on Cloudflare. This is a plain download. It sends none of your content.
3. Data we collect
Diagnostics and usage analytics
The app uses Google Firebase (Analytics, Crashlytics and Performance Monitoring) to find crashes, keep it fast and see which features are used. This data is not linked to your identity, and we do not use it to track you across apps or websites. The app contains no advertising code and never reads your advertising identifier. These are the data types involved:
| Data type | What it is | Why |
|---|---|---|
| Crash data | Crash reports: the app version, your device model and iOS version, and what the app was doing when it stopped | Fixing bugs, and analytics |
| Performance data | How long screens, exports and network calls take | Keeping the app fast, and analytics |
| Other diagnostic data | Technical details about the device and the app’s state, such as storage space and error codes | Fixing bugs, and analytics |
| Product interaction | Counts of actions such as opening a project, adding a watermark, exporting or viewing the Pro screen. Never the content of your projects | Analytics |
| Device ID | A random identifier that Firebase creates for this installation. It is not your advertising identifier | Analytics |
| Coarse location | An approximate area (such as city or country) that Firebase works out from your IP address. The app never asks for your location | Analytics |
We never send project or template names, watermark text, file names, photo details, or your email address to Firebase.
The app also reads a small settings file from Firebase Remote Config, which sets the limits of the free plan. This lets us adjust the limits without publishing a new version.
Purchases
Bulk Watermark Pro is bought through the App Store, and Apple handles your payment. We never see your card or payment details. RevenueCat manages Pro access for us. It receives an app user ID (anonymous unless you sign in, in which case it is your account ID), your purchase and subscription history, and basic device and connection details, so that it can tell whether Pro is active and restore it on your other devices.
Account data, if you sign in
An account is optional, and the app works fully without one. If you sign in with Apple or Google, our account service stores the email address and name your provider shares (Apple lets you hide your email), an account ID, and the identifiers and session details needed to keep you signed in. An account lets Pro follow you to your other devices.
Messages you send us
If you write to support@bulkwatermark.app, we receive your email address and your message, and we keep them for as long as we need to help you.
4. Data we don’t collect
- The content of your photos, or any of their metadata
- Your contacts
- Your precise location
- Your advertising identifier
- Anything for tracking you across other companies’ apps and websites
This website runs no analytics and sets no cookies of its own.
5. How we use data
- To run the app, and to find and fix crashes and slow spots
- To understand which features people use, so we can improve them
- To provide Pro and restore it when you ask
- To let you sign in and keep your account working
- To answer your messages
We do not sell your data, and we do not use it for advertising.
6. Service providers
These companies process data for us. Each receives only what is listed here.
- Google Firebase (Analytics, Crashlytics, Performance Monitoring and Remote Config): the diagnostics and usage data from section 3. See Firebase privacy and Google’s Privacy Policy.
- RevenueCat: purchase and subscription information. See RevenueCat’s privacy policy.
- Cloudflare: runs the account service for people who sign in, where it stores the account data above, hosts the watermark artwork catalog, and serves this website. Cloudflare may process connection details such as your IP address to deliver pages and protect them from abuse. See Cloudflare’s privacy policy.
- Apple and Google, if you use them to sign in: each confirms your identity and shares your email and name with us. See Apple’s privacy policy and Google’s Privacy Policy. Apple also processes your App Store payments.
- Email: messages to our support address pass through Cloudflare Email Routing to our Google Gmail inbox, and our replies are sent through Resend. See Resend’s privacy policy.
Some of these providers process data in countries other than yours, including the United States. We may also disclose data when the law requires it.
7. Retention and deletion
- Deleting your account in the app removes your account record from our server and also removes the projects stored on that device. It does not touch the photos in your Photos library.
- Purchase records stay. RevenueCat keeps the purchase record after an account is deleted, so that your purchases can still be restored. Apple keeps its own purchase records as well.
- Analytics and crash data follow the retention settings Firebase applies by default. It is not linked to your identity, so it cannot be looked up or deleted by person.
- Messages to support are kept for as long as we need to help you, and you can ask us to delete them.
8. Your choices
- Photos permission. You can change or withdraw it any time in Settings › Privacy & Security › Photos, or in the Bulk Watermark entry in the Settings app.
- Your account. You can delete it in the app, as described in section 7.
- Your data. To ask what we hold about you, or to have it corrected or deleted, write to support@bulkwatermark.app.
9. Children
Bulk Watermark is not directed at children under 13, and we do not knowingly collect personal data from them. If you believe a child has given us personal data, write to us and we will delete it.
10. Changes to this policy
We may update this policy as the app changes. The date at the top shows the latest version. If a change affects how we treat your data, we will say so in the app or on this page.
