Acceptance of These Terms
These Terms of Use apply to Bubble Level Pro, a measuring toolkit for iPhone and iPad published by GuruApps. By downloading, accessing, purchasing, subscribing to, or using Bubble Level Pro, you agree to these Terms, our Privacy Policy, and any applicable Apple App Store terms. If you do not agree, do not use the app.
Relationship to Apple Terms and EULA
Bubble Level Pro is distributed through the Apple App Store. Your download, purchase, subscription, renewal, cancellation, refund request, and use of Apple platform features may also be governed by Apple's App Store, Apple Media Services, payment, and device account rules.
Unless a separate custom end user license agreement is shown for Bubble Level Pro in App Store Connect or on the App Store, Apple's standard Licensed Application End User License Agreement applies to your license to use the app. These Terms supplement that license by describing Bubble Level Pro's app-specific rules, subscription terms, and measurement limitations.
License to Use Bubble Level Pro
Subject to these Terms and applicable App Store rules, GuruApps grants you a limited, personal, non-exclusive, non-transferable, revocable license to use Bubble Level Pro on Apple-branded devices that you own or control and as permitted by Apple's usage rules.
You may not copy, resell, redistribute, sublicense, modify, reverse engineer, attempt to derive the source code of, interfere with, or misuse Bubble Level Pro except where applicable law expressly permits such activity.
About the App
Bubble Level Pro is designed for home improvement, DIY projects, alignment, leveling, and quick everyday measurements. The app may include tools such as Bubble Level, Surface Level, Compass, Metal Detector, Laser Level, AR Ruler, Plumb Line, Vibration Meter, calibration controls, lock mode, sound and haptic feedback, flashlight controls, and related measuring features.
Measurement Limitations
Bubble Level Pro uses device sensors, camera input, augmented reality features, magnetometer readings, motion data, calibration settings, and environmental conditions to estimate measurements. Results can be affected by device model, case or accessory interference, magnetic fields, lighting, camera visibility, surface stability, sensor drift, calibration quality, software updates, and user handling.
Bubble Level Pro is not a certified professional measuring instrument. Do not rely on the app as the only source of measurement for critical construction, engineering, electrical, safety, legal, medical, navigation, industrial, or professional work. Always verify critical results with dedicated professional measuring equipment and qualified judgment.
Safe and Responsible Use
You are responsible for using Bubble Level Pro safely and lawfully. Do not use the app while driving, operating machinery, climbing, working near hazards, or performing any activity where distraction or inaccurate readings could cause injury, property damage, or unsafe conditions.
Tools such as the Metal Detector, Compass, AR Ruler, Laser Level, Plumb Line, and Vibration Meter provide sensor-based estimates only. The app does not guarantee detection of hidden wires, pipes, structural elements, dangerous materials, or other objects.
Permissions and Device Features
Some Bubble Level Pro features may request access to device features such as the camera, motion sensors, magnetometer, location services, flashlight, sound, or haptics. Certain tools may not work, or may work with reduced functionality, if required permissions are denied, unavailable, restricted, or disabled in device settings.
Your use of Apple device hardware and system features remains subject to Apple platform rules, operating system permissions, and your device settings.
Pro Subscription
Bubble Level Pro offers optional Pro features through an auto-renewing subscription. The subscription available at launch is Bubble Level Pro Monthly for $5.99 per month. Prices may vary by country or region, currency, tax treatment, Apple pricing rules, promotions, or App Store configuration shown at the time of purchase.
- Payment is charged to your Apple ID account at confirmation of purchase.
- The subscription automatically renews unless canceled at least 24 hours before the end of the current billing period.
- Your account may be charged for renewal within 24 hours before the end of the current billing period.
- You can manage or cancel your subscription in your App Store account settings after purchase.
- Deleting Bubble Level Pro does not automatically cancel an active subscription.
The subscription name, duration, price, renewal details, and included Pro features are shown in the app's purchase screen before you confirm a purchase. If the App Store purchase sheet or App Store listing shows terms that differ from this page, the terms displayed by Apple at the time of purchase control the purchase and billing process.
Restore Purchases and Access
Bubble Level Pro may provide a restore purchases option so current subscribers can restore eligible access on supported devices. Subscription access depends on Apple's purchase records, your Apple ID, App Store availability, network connectivity, and the app's ability to validate entitlement status.
Refunds
Purchases and subscriptions made through the App Store are processed by Apple. Refund eligibility, approval, timing, and payment reversal are controlled by Apple and applicable App Store policies. GuruApps cannot guarantee that a refund request will be approved.
Updates and Availability
GuruApps may update, change, add, remove, suspend, or discontinue Bubble Level Pro, Pro features, free features, tool behavior, compatibility, subscription offerings, or support for specific devices or operating system versions at any time, subject to applicable law and App Store rules.

Bubble Level Pro, including its name, design, code, interface, text, graphics, icons, screenshots, and related materials, is owned by GuruApps or its licensors and is protected by intellectual property and other laws. These Terms do not transfer ownership of any GuruApps intellectual property to you.
Third-Party Services
Bubble Level Pro may rely on Apple frameworks, App Store services, analytics, crash reporting, subscription validation, or other third-party services. We are not responsible for third-party services, and your use of them may be subject to their own terms, privacy policies, and technical limitations.
