Privacy Policy

Effective: 2026-05-17

K-emoji is a free, ad-supported app. Your photos are processed entirely on your device and are never uploaded to any server. However, the app includes third-party advertising that collects certain device and usage data. This page explains exactly what is collected, by whom, and why.

This page is provided in 18 languages for convenience. The English version is the official, governing version in case of any discrepancy.

What K-emoji does NOT collect

• Photos. Your photos never leave your device. We do not upload, transmit, or store any image data on our servers (we don't have servers for image data).
• Personal information. No name, email, phone number, address, or government IDs.
• Account data. There are no accounts to create or sign in to.
• Location. We do not request or collect location data.
• Contacts. We do not access your address book.

What K-emoji collects (anonymous, minimal)

Anonymous app usage analytics

To understand how features perform and find bugs, K-emoji sends a small set of anonymous usage signals via TelemetryDeck, a privacy-first analytics service. These signals contain things like:

• Which mode you used (Face / Background)
• Whether processing succeeded or failed (and the failure reason category)
• Approximate face count bucket (e.g., "1-3", "4-10")
• Save success / failure events

These signals do not include your photos, identifiers, names, or anything that could identify you personally. TelemetryDeck cryptographically hashes a coarse device identifier so individual users cannot be tracked.

Crash reports (Apple)

If the app crashes, anonymous crash data may be shared with Apple via your iOS device's standard diagnostics settings. You can opt out of this in iOS Settings → Privacy & Security → Analytics & Improvements.

Photo library access

K-emoji requests access to your photo library for two reasons only:

• Read access: So you can pick a photo to process.
• Add access: So the app can save the result to your photo library when you tap Save.

You can grant limited library access (only specific photos you select) instead of full access. Either way, processed images stay on your device.

Face detection — how it works

Face detection runs entirely on your device using Apple's Vision framework, which is built into iOS. No image data is sent to any server. Detection happens in milliseconds, locally.

Advertising (Google AdMob)

K-emoji is free and shows ads provided by Google AdMob. To serve and measure ads, the Google Mobile Ads SDK may collect the following data:

• Device identifiers — including the Advertising Identifier (IDFA) if you grant permission via Apple's App Tracking Transparency prompt.
• IP address — used for approximate geographic targeting and fraud prevention.
• Ad interaction data — which ads were shown, whether you tapped on them, and how long they were displayed.
• Device information — such as device model, OS version, and language settings.

This data is sent to Google's servers. K-emoji itself does not have access to this data — it is collected and processed by Google under Google's Privacy Policy.

App Tracking Transparency

When you first use K-emoji, iOS will ask whether to allow tracking. If you choose Allow, Google may use your device's Advertising Identifier to show personalized ads and measure ad effectiveness across apps. If you choose Ask App Not to Track, ads will still appear but will not be personalized. You can change this at any time in iOS Settings → Privacy & Security → Tracking → K-emoji.

Children's privacy

K-emoji is rated 4+ in the App Store. The app does not knowingly collect personal information from children. Since we don't collect personal information from anyone, this applies to all users regardless of age. Ads shown to children are non-personalized in accordance with Google's policies for child-directed content.

Third-party services

• Google AdMob — third-party advertising. Collects device identifiers, IP address, and ad interaction data. See the Advertising section above for details.
• TelemetryDeck — anonymous usage analytics. No PII.
• Apple PhotoKit — for reading and saving photos. Stays on-device.
• Apple Vision framework — for face detection. Stays on-device.

Data retention

Anonymous analytics are retained by TelemetryDeck per their policy. Ad-related data is retained by Google per their policy. The app itself does not retain your photos between sessions — once you exit the app, your selection is gone (the saved result remains in your Photos library where you saved it).

Your rights

Since K-emoji does not collect personally identifiable information, there is no personal data to access, correct, or delete. To revoke photo access, use iOS Settings → Privacy & Security → Photos → K-emoji. To revoke ad tracking, use iOS Settings → Privacy & Security → Tracking → K-emoji.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new effective date. Material changes will also be communicated via an in-app notice on the next launch.

Cookies & Local Storage

This site does not use any tracking cookies. The only browser storage we use is a localStorage entry that records your cookie-consent choice (accept or reject), so the consent banner doesn't appear on every visit. You can change your choice anytime by clicking Cookie settings in the footer of any page. If we add analytics in the future, they will only run when you have accepted.
