Luca Schick, email: dev@cailev.com. This policy applies to the Pagend: Page Blocker browser extension in Chrome, Opera, Edge, Brave, Vivaldi and Firefox, and to this page itself.
connect-src 'none'). External links open the relevant website in your browser.The extension stores on your device only what is strictly necessary for the feature you asked for (standard: § 25(2) no. 2 TDDDG, the German telecommunications and digital services data protection act). There are no cookies and no identifiers that could recognise you. The table shows what is stored and for how long.
| Kind | Example | How long |
|---|---|---|
| Settings and site list | Daily limit, daily limit per weekday, total limit, blocked hours, step plan, sites and sections that are on, own sections with the path you created yourself (such as /shorts), language, view and sort under “Sites”, modules with selection, star and order, your own texts to type, questions for the thought prompt, Instead suggestions, notice before the block, mindful start, grayscale, features that can be turned off, context menu entry, whether the step before the browser’s prompt should appear, deletion periods, backup reminder interval, automatic backup, four personal view adjustments under “Accessibility” (less motion, outlines, controls, text spacing, no diagnosis) | Until you change or reset them |
| Daily state | Minutes used today, unlocks, blocks, technical points in time for fair counting (start of the current measurement, end of extra time, last clock check) | Until midnight, then only daily totals go into the history if the switch is on. Points in time never go into the history |
| History | Daily totals per site: time used, blocks, unlocks, counters per module, pledges kept and not kept | Until you delete it or a deletion period applies |
| Reflections | Your own text with its question, answers to thought prompts too | Like the history, with its own deletion period. If storage runs low, the oldest texts go first |
| Recent thought prompts | Which questions came up last, without answers | Until the next round starts |
| Achievements | Counters, streak and the day a level was earned. Points and rank are calculated from them | Until you reset them |
| Technical details | Install date, data version, state of the setup and the switches, whether an explanation has appeared, number of texts and days removed automatically, last day of automatic deletion, notice of a step plan reduction, end of a focus time, day of the last backup (without time and content), hidden week of the weekly review, time and result of the last automatic backup with the download IDs of its own files | Until reset or removal |
| Copy before an update | Settings, sites and general options before a change of the data version, without history and without reflections | 3 days after the update |
| Fallback copies of the automatic backup | The last 2 automatic backups when saving a file didn’t work (no permission, no access, disk full) | Until a newer one replaces them, a deletion cleans them up or the extension is removed. They’re lost with the browser profile |
| Session data | Module in progress, text of an open pledge, a site you’re adding right now, which tab belongs to which site (site ID only), per site the time of the last visit for the mindful start, the kind of a problem while saving | At the latest until the browser closes, the visit after 30 minutes without the site |
| Working memory only | Reports that a tab is visible when “Visible windows” is on; the address of a page visit while it is compared with your list; your notepad during mental math; your answer to “Why are you opening … right now?”; after “Limit this site”, domain and path suggestion without query or anchor | At most 15 seconds, until the comparison, the next sum, the click or at most 2 minutes. Never stored |
| Original address | The full address after the # on the block page, for returning in the tab | As long as the tab is open. Your browser may keep it in its own history |
| Backup | File with site list, settings, features, history, achievements and, if you want, reflections | Until you delete the file yourself or the rotation of the automatic backup removes it |
Only sites on your list are recorded. Only the site itself is stored permanently, never an exact address, no path of a visited address and no page title, and only daily totals, not when exactly you were on a site. The extension only stores a path if you create it yourself as a section (“Only this section”), and then only that path, never query (?…) or anchor (#…). Through the webNavigation permission the extension learns about page visits on all sites, but only compares the address with your list. If the site isn’t on it, nothing happens and nothing is stored. It doesn’t read your saved browsing history.
A small script runs on sites you turned on. It sends the page address and whether the page is visible to the extension itself and nowhere else. It doesn’t read page content.
You can limit a site from the popup at the icon, by right-clicking a web page (contextMenus permission) and in Firefox also by right-clicking the tab. The extension only reads the page address after your click (activeTab or the click in the menu) and keeps only the domain and a path suggestion, in working memory only. You choose “Whole site” or “Only this section”. Nothing is stored until you actually add it: the domain, and with “Only this section” the path as an own section.
If you turn on automatic backup under “General”, the browser asks for the downloads permission. The extension then saves a backup daily, hourly or at your interval into a subfolder of your downloads folder. It only runs while the browser is running, and the file isn’t sent anywhere.
The extension uses the unlimitedStorage permission. It removes the 10 MB limit of local storage so old reflections and days don’t have to go. Your data stays on your device, and nothing additional is recorded because of it.
Before a change of the data version during an update, the extension makes a copy of the affected settings, without history and without reflections (migrationBackup). It is restored if something goes wrong, goes away 3 days after the update and is removed by “Delete absolutely everything”.
If the drive is full anyway, the extension removes the oldest reflections first, then the oldest days, and tells you on its pages. Only the number is kept for that. A backup copy never pushes out your data. Problems while saving are remembered only as the kind of problem, without any content, and only until the browser closes (storageIssues).
Reflections can be very personal, for example about mood or health. They only live on your device, can be turned off, read and deleted under “Privacy”, and only go into a backup if you want them to. The provider never receives them.
You don’t have to provide any data. Everything is voluntary, the extension also works without reflections and without history. There are no automated decisions about you and no profiling: the block only follows your own rules.
The extension doesn’t record any age information, and no data goes to the provider.
When showing a page, the extension detects which browser is running so the right texts appear. The result is never stored and never sent.
The Firefox package is built from the same source code and processes the same data in the same way. In the package, Mozilla is told that the extension collects no data (data_collection_permissions: none).
If you turn on the warning as a system notification, the browser asks for the notifications permission. The notification is created on your device and shown by the operating system. It isn’t sent anywhere.
“Info” shows the address for feature requests and bugs as an email link. A click opens your own email app. The extension doesn’t connect anywhere and sends nothing along, no data and no version.
Clicking the Ko-fi support button opens Cailev’s public Ko-fi page. The extension does not send your usage history, settings or reflections when opening it. Support is voluntary and does not affect the features of Pagend: Page Blocker.
When you make a payment, Ko-fi and the connected payment provider, PayPal, may make information about your contribution available to me. This can include a display name, email address, amount, time, optional message and other transaction details where applicable. In the PayPal payment details, I can see the name and email address of the person making the payment. I use this information as needed to identify payments, handle questions or refunds and meet legal obligations. The relevant bases may include my legitimate interest in handling contributions and applicable legal obligations (Art. 6(1)(f) and (c) GDPR). I retain payment records for as long as needed for these purposes or as required by law.
I do not maintain a separate supporter database, routinely export supporter data or use email addresses for newsletters or advertising. Depending on your choice, your display name and message may be visible on Ko-fi. A private message is still visible to me. See the privacy policies of Ko-fi and PayPal for how those services handle data.
When a suitable store link is available, Pagend may ask for a review no sooner than 14 days after the known installation date. It may ask again no sooner than 30 days after the last request was actually shown. “Don’t show again” saves your choice locally. Pagend stores the time of the last visible request and your opt-out. Older installations may also have a legacy display flag and a one-time waiting period. A short reservation in session storage prevents duplicate requests. These details are excluded from exports and are deleted when you delete absolutely everything or remove the extension. The store opens only when you click. Pagend does not learn whether you submit a review.
You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15 to 21 GDPR). The extension’s data only lives on your device, so you can exercise these rights yourself: under “Privacy” you see what is stored, read your reflections and delete specific items or everything. Under “General”, “Save backup” puts everything into a file you can take with you. For emails and any questions, contact dev@cailev.com.
You also have the right to lodge a complaint with a data protection supervisory authority, for example in the country where you live (Art. 77 GDPR).
The data isn’t encrypted. Anyone who can use your browser profile can read it, reflections too.
A backup file isn’t encrypted and contains your site list, your history and, if you want, your texts. There is no sync and no protection against files changed by hand.
A detailed explanation of every permission is in the extension under “Privacy”, in the section “What this extension can and can’t do”.
