Privacy policy
Updated 12 November 2026.
"Workshop: repairs and experiments" is a blog of our own repairs and experiments. This page explains in plain language what the site learns about visitors, why, how long it is kept, and what you can do about it. The blog's author is responsible for this data.
In short
| What | How it works here |
|---|---|
| registration, comments, mailing lists | none: we do not ask for your name, email or phone number |
| visit counters and analytics | none |
| advertising | Google AdSense in published articles; Google uses its own cookies (details) |
| technical server logs | yes, as on any website; kept for up to 4 months (details) |
| what you enter into the tools in articles | stays in your browser and is not sent to us (details) |
| selling data | never |
| sharing data | only with Google to show ads (details) and where the law requires it |
Technical server logs
Like any website, the server records technical details of requests: the IP address, the time, the page address, the browser name and version, and the server's response.
Why: to keep the site running, to find faults and to protect it from abuse, such as overly frequent automated requests and attempts to break in. We do not use these records to build a picture of any particular person, and we do not share them with anyone, except where the law requires it.
The logs are deleted automatically; the longest they are kept is 4 months.
Protection from automated requests
The site checks that requests come from a person rather than an automated program. To do this it may store a service cookie in your browser: it only confirms that the check was passed, says nothing about you and expires quickly. The site limits overly frequent requests of the same kind.
File downloads
Some articles have files attached. So that no single visitor uses up all the bandwidth, the number of downloads from one IP address is limited. For this the server keeps, for 48 hours, an encoded record that does not contain the IP address itself, together with the number of your downloads. Overall counters (how many times each file was downloaded, with no addresses at all) are kept for up to 400 days.
Tools in articles
Some articles include tools: measurement tables and calculators. What you enter into them is stored only in your browser's storage on your device and is not sent to the server. Clear the browser data for this site and it is gone.
Search
A search query is sent to the server as part of the page address so that articles can be found. Queries are not stored separately; the page address with the query only ends up in the technical logs.
Cookies
- The blog's own: the blog sets no cookies for visitors, apart from the service cookie for protection described above.
- A sign-in cookie is used only by the blog's author, to work in the article editor.
- Google's cookies are covered under "Advertising".
You can block cookies in your browser settings. The articles will mostly read just the same; the site may simply check more often that you are not an automated program.
Advertising
Published articles show Google AdSense ads. Third-party vendors, including Google, use cookies. Advertising cookies (including the DoubleClick cookie) enable Google and its partners to:
- show you ads based on your visits to this and other websites;
- limit how many times the same ad is shown;
- detect fraudulent clicks.
What you can do:
- Opt out of personalised advertising from Google in Google's ad settings.
- Opt out of personalised advertising from other vendors at aboutads.info.
- Visitors from the European Economic Area, the United Kingdom and Switzerland see a consent request from Google. Without consent, non-personalised ads are shown. You can change your choice at any time: clear this site's cookies in your browser and the request will appear again.
How Google uses data from sites that show its ads is explained on the page "How Google uses information from sites or apps that use our services". We do not control Google's cookies: Google decides what they contain and how long they last. We do not pass your measurements from the tools or your search queries to advertisers.
Children
The blog is not intended for children under 16, and we do not knowingly collect data about them.
Your rights
You can ask what data we hold about you, ask for it to be corrected or deleted, or object to its processing. We collect no names or accounts, so technical records can only be found by IP address and time of visit; please include them in your request. We reply as soon as possible, and within one month at the latest. If you believe your data is being handled wrongly, you can complain to the data protection authority in your country.
The legal basis: technical logs, protection from automated requests and download limits are needed to keep the site running and secure (legitimate interest); personalised advertising only happens with your consent.
Data collected by Google is controlled by Google: use Google's ad settings or contact the company directly.
Where data is processed
The site is available worldwide. Google processes data on its own servers, including outside Ukraine and the European Union.
Changes to this page
We update this page when the site changes. The date of the latest changes is at the top of the page.
