Privacy at Lift Heavy.

Last updated · March 25, 2026

Overview

Lift Heavy is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use our iOS application.

Information we collect

Lift Heavy stores the following information locally on your device:

• Workout sessions and exercise logs
• Custom workout plans
• Exercise library and preferences
• User profile settings (name, preferred formulas, timer settings)
• Progress tracking data

How we store your data

The vast majority of your data is stored locally on your device. We do not:

• Collect or store personal information on our servers
• Sell your data to anyone
• Link any of the data described below to your name, email, or account

Three paths send data off your device — a Capture photo scan, a Capture voice or text parse (both only when you use them), and Advertising (only on the free tier). All three are detailed below.

Capture (AI workout capture)

Capture is optional. Nothing is logged until you review and confirm it. A free account gets 3 photo scans and 10 voice or text parses each month — two separate allowances — and Pro removes both limits.

Photo scans

• The photo you capture is sent to our secure server for processing by an AI model (Anthropic Claude, delivered through AWS).
• The image is used solely to extract workout information (exercises, sets, reps, weights) and is not stored on our servers after processing.
• No images are retained, logged, or used for training purposes.
• Your subscription status is verified via Apple's signed transaction tokens.

Voice and text

Your voice is transcribed on your device. (Workout structuring uses AI and is provided in English.) That means the audio itself never leaves your device — only the resulting text does, and it goes to the same AI service that handles photo scans, where it is used only to structure the workout and is not retained.

In-app purchases

Lift Heavy offers optional subscriptions and one-time purchases. All transactions are processed securely through Apple's App Store. We do not collect or store any payment information. Apple may share transaction receipts with us for the purpose of verifying your purchase status.

Permissions

Lift Heavy requests the following permissions:

• Notifications: To alert you when rest timers complete during your workouts. You can disable this in your device settings at any time.
• Siri: To enable voice commands for hands-free workout logging. Voice processing is handled by Apple's Siri system.
• Camera & Photo Library: The camera is used to take a photo for Capture and to take a photo for a workout share card. The app writes to your photo library only when you save a share-card image; choosing an existing photo for Capture goes through the system photo picker, which gives the app only the photo you select, not access to your library.
• Microphone & Speech Recognition: The microphone lets you speak a workout aloud, and Speech Recognition transcribes what you said on your device to turn it into a logged workout.

Data security

Your workout data is stored securely on your device using iOS's built-in security features. For Capture, both the photo and the transcribed text are transmitted over encrypted HTTPS connections and are not persisted on our servers.

Data backup

Your Lift Heavy data may be included in your device's iCloud or iTunes backups if you have those features enabled. This is controlled by your device settings, not by Lift Heavy.

Children's privacy

Lift Heavy does not knowingly collect information from children under 13. The app is designed for general fitness tracking and does not require age verification.

Your rights

You have complete control over your data:

• All data is stored on your device and can be deleted by uninstalling the app.
• You can delete individual workout sessions or exercises within the app.
• No account creation or personal information is required to use Lift Heavy.
• You can manage or cancel subscriptions at any time through your Apple ID settings.

Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the "Last updated" date above. Continued use of Lift Heavy after changes constitutes acceptance of the updated policy.

Use of TelemetryDeck to analyze app usage

We use the privacy-friendly analytics service TelemetryDeck (provider: TelemetryDeck GmbH, Von-der-Tann-Str. 54, 86159 Augsburg, Germany) to analyze usage data. The use is based on Art. 6 para. 1 lit. b GDPR, as we require reliable and efficient tools for collecting app usage data in order to fulfill the contract with you, our customer.

What data is transferred?

The data processed by TelemetryDeck is completely anonymized and does not allow any conclusions to be drawn about personal information. The following data is collected, among other things:

• An anonymized, untraceable user ID (per app installation)
• Actions defined by the app publisher (e.g., "app launched," "settings opened")
• A rounded timestamp (to the nearest hour)
• Device metadata (e.g., system version, app version, device type)
• Additional metadata defined by the app publisher (e.g., "number of items in the database")

What is not stored?

• No IP addresses (not in logs, not in the database)
• No cookies or tracking technologies
• No persistent identifiers that could be traced back to individuals

The source code of the TelemetryDeck SDK is completely open source and available on GitHub: https://github.com/TelemetryDeck

Further information on the exact data processing by TelemetryDeck can be found at telemetrydeck.com/privacy and telemetrydeck.com/docs/guides/privacy-faq/.

Advertising

The free tier of Lift Heavy displays ads served by Google AdMob. Pro subscribers do not see ads. AdMob is the only ad network we use.

When AdMob serves an ad on your device, it may collect a limited set of data that is not linked to your identity — we do not pass your name, email, or any account information to AdMob:

• Device identifiers — a device identifier used by AdMob to frequency-cap ads and prevent fraud. Lift Heavy does not request Apple's advertising identifier (IDFA) — we do not show the App Tracking Transparency prompt.
• Coarse location — approximate region (typically city- or country-level) inferred from your IP. Lift Heavy never requests precise GPS location for advertising.
• Product interaction — which ad you saw, whether you tapped it, and which screen it appeared on.
• Advertising data — campaign and creative identifiers used by AdMob for measurement.

Apple's App Store privacy labels classify all four data types as Data Not Linked to You.

Attribution

Lift Heavy uses Apple's privacy-preserving SKAdNetwork framework to measure ad campaign performance without exposing your identity to advertisers.

Your choices

• Subscribe to Pro — removes all ads.
• iOS Settings → Privacy & Security → Apple Advertising — turn off "Personalized Ads" to disable Apple's own ad personalization.
• EU / UK / EEA / Switzerland — on first launch, AdMob's Google User Messaging Platform (UMP) presents a GDPR consent dialog where you can grant or refuse advertising consent.
• California residents — you have the right under the CCPA to opt out of the sale or sharing of personal information. Although Lift Heavy does not send any personally identifying data to AdMob, you may exercise this right by emailing support@lfthvy.app.

Third-party services

Lift Heavy integrates with the following third-party services:

• Apple App Store — For processing in-app purchases and subscriptions.
• Anthropic Claude (via AWS) — For AI-powered analysis of a captured workout image and for structuring a transcribed or typed workout (only when you use Capture).
• TelemetryDeck — For privacy-friendly, anonymized app usage analytics (described above).
• Google AdMob — For serving ads on the free tier (described above). Pro subscribers do not see ads.

Website analytics

This website (lfthvy.app) uses Google Analytics 4 to understand how visitors use our marketing site. This is separate from TelemetryDeck, which analyzes usage of the Lift Heavy iOS app as described above — Google Analytics never sees any in-app data.

Analytics cookies are not set until you accept them in the cookie banner shown on your first visit. If you reject or take no action, no Google Analytics cookies are stored for your visit.

What Google Analytics collects (only if you accept)

• Pages viewed — which pages you visit and how long you spend on the site.
• Referring site or search term — what led you here.
• Approximate location — country- or city-level, derived from your IP address.
• Device and browser type — what device and browser you're using.

What it does not do

• No advertising — no ads run on lfthvy.app and Google Analytics is not connected to any advertising network.
• IP truncation — Google Analytics automatically truncates IP addresses before storage; this is not a setting we enable or disable, it is how GA4 behaves by default.
• No data sale — we do not sell website visitor data to any third party.

Your choices

• Reject in the cookie banner — no analytics cookies are ever set for your visit.
• Clear your browser's site data for lfthvy.app — resets your choice; the cookie banner will appear again on your next visit.
