Who is responsible

Using the site without an account

You can use every comparison without signing in. Your filters, settings and saved presets are then kept in your browser's local storage and are not sent to us. To deliver pages, our server necessarily processes technical request data such as your IP address, the requested page and your browser type; this is used to run and secure the service (Art. 6(1)(f) GDPR) and, without your IP address, for the aggregate visitor statistics below. We use no tracking or advertising of any kind.

Visitor statistics

To see which pages are read and how people find the site, our server counts the page loads it delivers. For each day it stores only totals per page and referring website: the number of page loads (opening or reloading a page; moving between pages inside the site is not counted), the number of visits (page loads that did not come from another page of this site), the requested page (without query parameters) and the host name of the website that linked to it (for example news.ycombinator.com, without path or query).

• What is used: only HTTP headers your browser sends with the page request itself — the Referer header (reduced to the host name), the User-Agent header (read in full, only to leave out automated clients, and not stored), the Accept, Sec-Fetch-Dest and Sec-Purpose/Purpose headers (to tell a page load from a prefetch or a file request) and the Global Privacy Control / Do Not Track signals. These are processed in memory; only the daily totals are kept.
• No device access and no identifiers: the statistics set no cookie, use no local storage, add no script, pixel or extra request, and do not use your IP address. No ID, hash or fingerprint is created, so we cannot count unique visitors or tell whether two page loads came from the same person, and statistics are never linked to accounts. In our assessment no consent is required under § 25 TDDDG for this, so there is no cookie banner.
• Purpose and legal basis: understanding which content is useful and planning capacity; our legitimate interest under Art. 6(1)(f) GDPR.
• Where and who: the totals are kept in our own database on servers of Hetzner Online GmbH in the European Union, which acts as our hosting processor. No analytics provider is involved and nothing is passed to anyone else. Our internal report only shows pages and referring websites with at least 3 page loads; those with fewer than 3 are combined.
• Retention: daily totals are deleted after 13 months (checked at least hourly). Totals not yet written are held in server memory, normally for about a minute and never for more than two days.
• Objection: if your browser sends a Global Privacy Control or Do Not Track signal, your page loads are not counted at all. As the stored totals cannot be traced back to you, we cannot find or remove past counts of a single person; you can still object by email to info@productivity-boost.com, and we will answer and explain how to switch on one of these signals.

Accounts (Sign in with Google)

If you choose to sign in, Google shares your Google account ID, email address, name and profile picture link with us. We store exactly these, the presets and settings you save, and when the account was created and last signed in to. We use them only to provide your account and sync your presets and settings across browsers (Art. 6(1)(b) GDPR). Sign-in itself is handled by Google Ireland Limited under its privacy policy.

While you are signed in, strictly necessary cookies keep the session (for up to 30 days) and protect sign-in requests against forgery. They are required for the account to work (§ 25(2) TDDDG).

Deleting your data

Your account data is kept until you delete it. On the Account page, “Delete my account and data” removes your account, presets and settings from our database immediately. You can also ask us by email.

Hosting

The site and its database run on servers of Hetzner Online GmbH in the European Union, acting as our processor. Your data is not sold or shared for advertising.

Your rights

You have the right to access, rectify and erase your data, to restrict or object to its processing, and to data portability. You may also lodge a complaint with a data protection supervisory authority, for example the Bavarian Data Protection Authority (BayLDA).
