Privacy Policy

Toolbox does not collect your data. This page explains what stays on your device, what the permissions are used for, the few cases where Toolbox talks to the internet, and the anonymous visitor statistics of this website.

Effective date: October 26, 2026

Who is responsible

Christian Nagel, toolbox@sivery.de. More contact details are in the imprint.

No tracking, no accounts

Toolbox has no user accounts, no analytics, no advertising and no crash reporting service. Nothing you do in the app is sent to me or to anyone else.

Data that stays on your device

Some tools remember things for you, for example your settings, the order of the tools, scanned barcodes and your Wake On Lan devices. This data is stored only on your device. It is removed when you use "Delete Data" in the app's info screen or delete the app.

Permissions

Toolbox only asks for a permission when you open a tool that needs it. Everything is processed on your device.

• Camera: to read barcodes and QR codes, to show the camera full screen and on a connected display (Fullscreen Camera), and to show scrolling text on the back display. The picture is only shown, never recorded or stored.
• Microphone: for the Decibel Meter. Only the sound level is measured, no audio is recorded or stored.
• Location: to show your coordinates, your speed and your position on the Distance map. The Speed tool may ask for your precise location once, because speed can't be measured without it.
• Local network: for the LAN Scanner, Ping and Wake On Lan.
• Photos (add only): when you save a shared image, such as a QR code, to your photo library. Toolbox can't see your photos.
• Files: to select a font file you want to install. You pick the file yourself; Toolbox gets no access to your other files.

Tools that use the internet

Some tools only work by sending a request over the network. These requests go directly from your device to the destination, never through a server of mine:

• Ping, Domain Resolver, LAN Scanner and Wake On Lan contact the addresses you enter or the devices in your network. To look up a domain name, Ping and Domain Resolver ask the DNS server your network is set up with.
• IP-Checker asks checkip.amazonaws.com, a service of Amazon Web Services, for your public IP address. Like every website, this service sees your IP address when you open the tool. See the AWS Privacy Notice.
• Distance shows an Apple Maps map and asks Apple for the names of the places you mark. See Apple's Privacy Policy.
• Font Installer starts a small web server on your device for a moment, so that Safari can open the font profile. It can only be reached from your device itself.

Links to other websites

The app links to this website, the newsletter, the App Store, Buy Me a Coffee and, in the BMI tool, Wikipedia. When you open such a link, the privacy policy of that website applies.

This website

This website uses no cookies and no external fonts. Like every web server, the server that hosts it records technical access data (IP address, date and time, requested page and browser type) to deliver the pages and keep the server secure. These logs are deleted after 180 days.

Visitor statistics with Plausible

To see how many people visit this website and which pages they read, it uses Plausible, a privacy-friendly analytics tool. Plausible runs on my own server at analytics.sivery.de; the data is not passed on to anyone else.

Plausible sets no cookies and stores nothing on your device. Your IP address is not stored: to count unique visitors, it is combined with your browser's user agent and a random value that changes every day, and turned into an anonymous identifier that cannot be traced back to you. After 24 hours even that is no longer possible. What is recorded is only aggregated: the pages visited, the website you came from, your country, browser, operating system and device type.

The legal basis is my legitimate interest in understanding how the website is used (Art. 6 (1) (f) GDPR). Since no personal data is stored, there is nothing to opt out of; blocking the script in your browser, for example with a content blocker, works too. The app itself contains no analytics.

Your rights

Under the GDPR you have the right to access, correct and delete your personal data, to restrict or object to its processing, and to lodge a complaint with a data protection supervisory authority. Since the app does not collect data, there is usually nothing stored about you. Just write to toolbox@sivery.de if you have questions.

Children

Toolbox does not collect data from anyone, including children.

Changes

If Toolbox changes in a way that affects your privacy, this page is updated and the effective date above changes.
