Privacy policy

Last updated: 15 September 2026

What the app stores, and where

Easy Modbus saves the following on your phone, and nowhere else:

• The devices you add — address, port, unit ID and name.
• The register maps you build — addresses, data types, scaling, units and notes.
• Any custom control screens you create.
• Your choice of Easy or Pro mode.

This data is deliberately excluded from Android cloud backup and from device-to-device transfer, because a register map names a customer's equipment. That does mean it does not follow you to a new phone; the CSV export is the way to move a map.

Advertising

The free version shows occasional rewarded video ads, supplied by Google AdMob, in exchange for exporting a report or opening a saved custom remote. To serve them, Google's advertising SDK may collect a device advertising identifier and standard ad-delivery information. How Google uses that data is described in Google's Privacy Policy and in How Google uses information from sites or apps that use its services. In the EEA, the UK and Switzerland you are asked for consent before any personalised ad, and may choose non-personalised ads instead. The one-time in-app purchase removes all advertising and also unlocks unlimited custom remotes. The developer receives only aggregate, anonymous earnings figures from AdMob — never your data.

What leaves the phone

Two things, both only when you ask for them:

• Modbus requests to the equipment you point the app at, on your local network.
• A CSV export, when you tap Export. The file is written to the app's cache and handed to whichever app you choose to send it with. Easy Modbus has no server and does not upload it anywhere.

Website analytics

This website, easymodbus.com, uses Google Analytics (GA4) to understand which guides are useful and how visitors arrive. It is loaded with Google Consent Mode: no analytics cookie is set and no data is sent until you choose Accept on the cookie banner. If you decline, or ignore the banner, Analytics stays off. Your choice is remembered in your browser and you can clear it any time by clearing this site's data. IP addresses are anonymised, and no advertising or cross-site tracking signals are collected on the website. Google's handling of Analytics data is described in Google's Privacy Policy. This is separate from the app, which contains no analytics at all.

What the app does not do

• No account, sign-in, or registration.
• No analytics, telemetry, or crash reporting inside the app itself. (The website uses Google Analytics with consent — see Website analytics above.)
• No location, contacts, photos, or microphone access.
• No internet use beyond talking to the equipment you point it at.

Permissions

• Internet and network state — to open TCP connections to Modbus equipment, and to find out which local network the phone is on so it can be swept.
• Wi-Fi state — to read the local address and subnet.

Your choices

• You can reset or delete your advertising identifier, or turn off ad personalisation, in Android Settings → Privacy → Ads.
• Where a consent prompt applies, you can change your answer at any time; declining simply leaves you with non-personalised ads.
• The one-time purchase removes advertising entirely.
• To erase everything the app has stored, uninstall it — nothing is kept anywhere else.

Children

Easy Modbus is a tool for building and industrial equipment and is not directed at children. It collects no personal information from anyone.
