Effective Date: November 10, 2026
This Privacy Policy applies to AR Ruler: Phone Tape Measure (package name: com.ssoft.arruler), a measuring app developed and published by SmartApps Team ("we", "us", "our").
It explains what information is collected when you use the app, how it is used, and the choices you have. By using AR Ruler, you agree to the practices described in this Privacy Policy.
Information We Collect
AR Ruler does not require you to create an account or sign in.
We do not collect personal information such as:
Name
Email address

Contacts or files on your device
The camera is used only to measure. Camera images are processed on your device while you measure. We do not upload, record or store them on our servers. A photo is saved only when you choose "Save photo", and it is stored on your device only.
The app may automatically collect limited information through the third-party services listed below. This information is not used by us to identify you personally.

Google Play Services
Google Play Services for AR (ARCore), used to track the camera position and detect surfaces
Google AdMob (advertising)
Google User Messaging Platform (consent management)
Firebase Analytics and Firebase Crashlytics (usage statistics and crash reports)
These services may automatically collect information including:
Device model and Android version
App version and device language
Advertising ID
IP address, which may be used to estimate your general location (country or region)
Ad interactions, such as ads viewed or tapped
Diagnostic information related to ad delivery
Crash reports and app usage events, such as which screen was opened or whether a measurement was completed (the measured values and your photos are not included)
Information that Google Play Services for AR processes to make augmented reality work, as described by Google

How We Use Information
The information collected through third-party services is used solely to:
Display advertisements, including rewarded ads you choose to watch
Limit how often ads are shown
Measure ad performance and prevent ad fraud
Find and fix crashes and understand which features are used
Keep the app working properly on different devices
We do not sell, rent, or share your personal information with third parties for their own marketing purposes.
Advertising and Your Choices
AR Ruler is free to use and is supported by ads shown through Google AdMob. The app shows:
Banner ads at the bottom of the screen
App-open ads when you open the app or return to it after some time
Interstitial ads after some of your measurements
Rewarded ads, only when you choose to watch one to unlock a feature for one use (for example PDF or CSV export, depth mode, floor plan export, or creating a new project)
Google and its advertising partners may use device identifiers and other information to provide, personalize and measure ads.
Your choices:
Consent: In some regions, including the European Economic Area, the United Kingdom and Switzerland, the app asks for your consent through Google's consent form before personalized ads are shown. You can change your choice at any time in Settings > Ad privacy choices.
Advertising ID: You can reset or delete your Advertising ID, or opt out of ads personalization, in your Android device settings (Settings > Google > Ads, or Settings > Privacy > Ads, depending on your device).
Rewarded ads are always optional. You can use all the free features without watching them.
Your Measurements and App Data
All measuring runs on your device, and the app works offline (an internet connection is only needed to load ads).
To keep your work, the app stores the following data on your device only:
Measurement history, labels and the points you placed
Photos you chose to save
Projects, rooms and floor plans
Files you exported (PDF, CSV or images), which are saved where you choose or shared by you
Settings such as units, precision, sound, vibration and screen ruler calibration
Whether a rewarded unlock has been used
We do not upload your measurements, photos, projects or settings to our own servers.
Measurements are estimates. They can be affected by lighting, surfaces, phone model and how you move the phone, so please do not rely on them where accuracy is critical.
Permissions
AR Ruler only requests the following permissions:
Camera: to measure distances and surfaces with augmented reality. The app asks you before using the camera, and you can still use the on-screen ruler if you decline.
Internet and network state: to load and display ads and to send crash and usage reports.
Advertising ID (com.google.android.gms.permission.AD_ID): used by Google AdMob for advertising and analytics.
Vibration: for haptic feedback while measuring, which you can turn off in Settings.
The app does not access your microphone, location services, contacts, or your photo library. Saved photos and exported files are written with the Android system file storage, without asking for access to your other files.
Data Storage, Retention and Deletion
We do not operate servers that store your personal information, measurements or photos. Any data stored by the app stays on your device.
Information collected by Google AdMob, Firebase and Google Play Services is retained according to Google's own data retention policies.
You can delete your data at any time by:
Deleting items inside the app (a measurement, a project, or a saved photo)
Clearing the app's storage in Android Settings > Apps > AR Ruler > Storage
Uninstalling the app
Photos and exported files that you saved to your device's gallery or storage are not removed when you uninstall the app, so delete them from there if you no longer want them.
Once removed from your device, we keep no copy of your data.
Security
We take reasonable measures to protect your information. However, no method of electronic storage or internet transmission is completely secure.
Children's Privacy
AR Ruler is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, please contact us and we will take steps to delete it.
Your Rights
Depending on where you live (for example, under the GDPR in the European Union or privacy laws in California and other US states), you may have the right to access, correct, delete or object to the processing of your personal information, and to withdraw consent. Because we do not store personal information on our own servers, most requests are handled through the options above or directly with Google. You can also contact us using the details below.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time, for example if we add new features or services. Any changes will be posted on this page with a revised Effective Date.
