Recommendations

"I had the pleasure of working with Adis for almost 2 years, and he is truly one of the best mobile developers I've worked with. His expertise in both iOS and Android development, combined with his problem-solving skills and strong attention to detail, made a huge impact on our team.

Adis is not only technically skilled but also a great team player. He communicates effectively, takes ownership of his work, and consistently delivers high-quality solutions. His ability to balance speed and precision helped us ship features efficiently without compromising quality.

Any team would be lucky to have Adis, ours still misses him, I highly recommend him to anyone looking for a top-tier mobile developer!"

NearBLE

Privacy Policy

This Privacy Policy explains how NearBLE handles information when you use the app.

Effective date: March 28, 2026

Overview

NearBLE is a Bluetooth Low Energy scanner that helps users discover nearby BLE devices, inspect their broadcast data, save scan history, and access AI-powered device explanations through an optional subscription.

Information NearBLE accesses

Bluetooth data required to discover nearby BLE devices, including broadcast names, signal strength, manufacturer data, advertised services, and connection state when available.
Subscription status information provided by Apple to determine whether NearBLE Pro is active.
Questions you submit to the AI feature together with relevant BLE context for the selected device.

How information is used

To scan for and display nearby BLE devices.
To save scan history and favorites locally on your device.
To provide AI explanations for BLE devices when you use the Ask AI feature.
To restore and manage subscription access through Apple.

Data storage

NearBLE stores scan history, favorites, and related app data locally on your device unless otherwise stated. NearBLE does not require account creation to use the core scanning experience.

AI feature

When you use Ask AI, the question you type and relevant BLE device context are sent to a third-party AI provider to generate a response. Do not submit sensitive personal information through the AI chat.

Third-party services

NearBLE may rely on Apple services such as StoreKit for subscriptions and system purchase handling, and on a third-party AI provider for Ask AI responses.

Your choices

You can deny Bluetooth permission, but scanning features will not work.
You can stop using the AI feature at any time.
You can manage or cancel your subscription in your Apple Account settings.

Contact

If you have questions about this Privacy Policy, please contact the developer through the support information provided with the app listing.
