Privacy Policy

Effective Date: June 4, 2026

StickerWords respects your privacy. This Privacy Policy explains how our app handles information when you use StickerWords, including camera-based vocabulary learning, object recognition, word saving, and learning progress features.

By using StickerWords, you agree to the practices described in this Privacy Policy.

1. Information We Collect

StickerWords is designed to collect as little personal information as possible.

We do not require you to create an account, register, or log in. We do not collect your name, email address, password, or profile information.

The app may process the following types of data:

Camera Images

When you use the camera feature, you may take or select an image so StickerWords can identify objects, signs, food items, or other visual content for language learning.

Images are used only to provide object recognition and vocabulary results. We do not store your images on our own servers.

Learning Data Stored on Your Device

StickerWords may save your vocabulary words, stickers, learning progress, review history, and spaced repetition data locally on your device.

This data is stored on your phone and is not linked to an account because StickerWords does not use login or registration.

App Usage and Analytics Data

We use PostHog to understand how users interact with the app and to improve the product. This may include information such as:

• App screens viewed
• Features used
• Button taps or learning activity events
• Device type
• App version
• General usage patterns
• Crash or performance-related information

We use this information to improve StickerWords, fix bugs, understand which features are useful, and make the app easier to use.

We do not use PostHog to collect your name, email address, password, or account details.

2. How We Use Information

We use information for the following purposes:

• To identify objects, signs, food items, or other visible content in images
• To provide vocabulary words and example sentences in your target language
• To save your learning progress locally on your device
• To support spaced repetition and daily review features
• To improve app performance, reliability, and user experience
• To understand which features are useful through analytics
• To detect and fix bugs or technical issues

3. Image Processing by Third-Party AI Services

StickerWords uses third-party AI services to process images and generate learning results.

These services may include:

• OpenAI
• Google Gemini

When you use image recognition features, the image you provide may be sent to these services for processing. The purpose of this processing is to identify what appears in the image and generate vocabulary-related learning content.

We do not store your images on our own servers. However, third-party AI providers may process data according to their own terms, privacy policies, and data retention practices.

You should avoid taking or uploading images that contain sensitive personal information, such as identity documents, financial information, private messages, medical records, or other confidential content.

4. Local Storage on Your Device

StickerWords stores your saved vocabulary, stickers, review progress, and learning history on your device.

Because StickerWords does not use login or cloud accounts, this data generally stays on your phone. If you delete the app, this local data may also be deleted, depending on your device and operating system settings.

We do not have access to your locally stored learning data unless you explicitly share it with us, for example when contacting support and choosing to provide screenshots or diagnostic information.

5. No Account or Registration

StickerWords does not require account creation, login, or registration.

This means we do not collect or store account credentials, usernames, passwords, or user profiles.

6. Third-Party Services

StickerWords uses third-party services to operate and improve the app:

PostHog

We use PostHog for analytics and product improvement. PostHog helps us understand app usage, improve features, and fix issues.

OpenAI

We may use OpenAI services to process images and generate vocabulary-related results.

Google Gemini

We may use Google Gemini services to process images and generate vocabulary-related results.

These third-party services may process data according to their own privacy policies and terms. We recommend reviewing their privacy policies for more information.

7. Data Sharing

We do not sell your personal information.

We may share limited data with third-party service providers only when necessary to operate the app, such as analytics providers and AI processing providers.

We may also disclose information if required by law, regulation, legal process, or government request.

8. Data Retention

StickerWords does not store your images on our own servers.

Learning data such as saved words, stickers, review history, and progress is stored locally on your device for as long as you keep the app installed or until you delete the data.

Analytics data may be retained by PostHog according to its own data retention settings and policies.

Images or prompts processed by OpenAI or Google Gemini may be handled according to those providers’ own data retention practices.

9. Children’s Privacy

StickerWords is intended for general language learning use. We do not knowingly collect personal information from children.

If you believe a child has provided personal information through the app, please contact us at [Your Email Address], and we will take appropriate steps to address the issue.

10. Your Choices

You can control your data in the following ways:

• You can choose not to use the camera or image recognition features.
• You can avoid uploading images that contain personal or sensitive information.
• You can delete locally stored app data by deleting the app from your device.
• You can contact us with privacy-related questions or requests.

11. Security

We use reasonable technical and organizational measures to protect information processed through StickerWords.

However, no method of transmission or electronic storage is completely secure. We cannot guarantee absolute security.

12. International Data Processing

Third-party services used by StickerWords may process data in countries other than your own. By using the app, you understand that data may be processed by service providers outside your country of residence.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make changes, we will update the “Effective Date” at the top of this policy.

Your continued use of StickerWords after changes are made means you accept the updated Privacy Policy.
