How Bingo Card Maker handles data

Bingo Card Maker uses the words, numbers and names you enter to generate bingo cards, call lists, cut slips and random groups. This policy describes the extension's saved records, its export actions, and the external services used by its welcome page and feedback links.

Inputs and exports

  • Lists you enter: the open workspace holds your current input. Use Save list to retain a list for a later session. Typing or pasting an unsaved list does not create a saved-list record.
  • Lists you save: each record includes an id, a list name, its items and its creation time. A list can include personal information, such as the names of people you enter.
  • Cards and groups: the extension generates these results from the input and a random seed. A reprint record is created when a generated card set matches a saved list. It contains the seed, card settings, list id and generator version, rather than the generated cards.
  • Export actions: Download PDF creates a PDF download. Print passes the rendered output to Chrome's print dialog. Group output can be copied to the clipboard, downloaded as CSV or printed. Chrome and the destination you choose determine how a download or print job is handled.

Extension storage

The extension uses Chrome extension storage with these keys:

  • bingoCardMaker.v1: saved lists, the last reprint record, remembered controls, an export counter and an optional rating-prompt record. Controls include grid size, free space, shuffle mode, card count, cards per page, paper, ink saver, theme, font, card title, call list, cut slips and group/CSV preferences.
  • bingoCardMakerRatePrompt: rating-prompt timestamps and the fact that the prompt was answered or dismissed. The product also mirrors rating state in the main preferences record.

The workspace can show its rating prompt after two successful PDF exports in a session, provided a previous prompt has not been recorded. Answering or dismissing it is recorded to suppress later prompts.

External pages and requests

  • Welcome-page counter: opening the packaged welcome page loads an image from mc.yandex.ru, Yandex Metrica counter 41115469. Its URL includes the fixed page label https://optkit.ru/welcome/bingo-card-maker. The image request exposes connection metadata, including an IP address and browser-provided request headers, to that service. Cookies may be sent or set subject to browser settings and the service's response. Reopening or reloading the welcome page can issue the request again.
  • Feedback after removal: Chrome may open the configured Google Form when the extension is removed. Chrome receives the form URL through its uninstall-URL API. Submitting a response shares the information you enter with the form operator and Google.
  • Rating links: choosing one, two or three stars opens the configured feedback Google Form. Four or five stars opens the product's Chrome Web Store reviews page when its store id is configured. Until that id exists, the extension shows an unavailable-page message. Google handles visits and submissions under the terms of its services.
  • Privacy page: this page is hosted on Cloudflare Pages. Visiting it sends a web request to that hosting service. Its contact link opens the configured Google Form.

Retention and deletion

  • Saved lists: retained until you delete them or remove the extension. Up to 50 lists can be saved; an additional save is refused.
  • Last reprint record: replaced by a later generated set that matches a saved list. Deleting the referenced list removes the reprint link; its seed and settings remain until replaced or the extension is removed. Removing the extension also removes its extension-storage records.
  • Remembered controls and rating state: retained in extension storage until changed or removed with the extension.
  • Unsaved workspace input and group results: held by the open workspace. Save or export the information you intend to keep before closing that workspace.
  • Exports: downloaded PDFs and CSVs, copied text and printed output are separate from extension storage. Deleting a saved list or removing the extension does not delete those copies.

Removal of the extension does not retract requests already made to Yandex, Google or this page's hosting service, or delete submitted form responses. Contact the operator about those records using the form below.

Permissions and execution

The extension requests the storage permission for the records described above. Card generation uses the packaged code and font assets; PDF generation runs in an extension worker. Browser profile access, clipboard contents, downloaded files and print destinations have their own access controls.

Privacy questions and requests

Use the contact form below to ask about information submitted through feedback forms, the welcome-page counter or a privacy request. Identify the relevant service and provide enough context to locate your request. Saved-list deletion and export deletion are separate actions, as described above.

Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
