Privacy Policy
California and United States privacy notice for Gridfunction at gridfunction.pages.dev.
Last updated: November 12, 2026
Gridfunction is a browser-based graph paper generator. The main paper and image-editing tools run on your device. This notice describes what the site itself uses, and what the hosting and advertising providers may process when you visit. This policy applies to the Gridfunction website, not to other websites you might visit from it.
1. Personal information: notice at collection
Before interacting with our tool or optional Google advertising, review the categories below. Data handling differs depending on whether you have opted out of advertising requests or have Global Privacy Control (GPC) enabled in your browser.
| Category & source | Why used | Disclosures or sharing | Retention |
|---|---|---|---|
| Technical and network data such as IP address, request URL, user agent and request timing, received by Cloudflare when your browser accesses the website. | Serve pages, operate the website, prevent abuse and protect the service. | Cloudflare processes this information as our hosting and security provider. It may be disclosed as required for legal or security purposes. | Cloudflare manages retention according to its services and applicable policies; Gridfunction does not maintain its own visitors' log database. |
| Paper preferences such as grid type, spacing, colors, paper size, and locally stored advertising opt-out preferences, entered by you or saved in browser storage. | Restore your design preferences and remember privacy choices on your device. | Saved locally in your browser; not sent to a Gridfunction application server. Shared-design URLs can expose included settings to people with whom you share that link. | Until you clear site data or browser storage; an optional opt-out cookie may persist up to one year. |
| Uploaded image content selected by you in the paper editor. | Preview, distort, print and export your design in the browser. | The editor does not send the image file to Gridfunction's servers. Images are only handled in your current browser session. | In-memory until you close or reload the page, remove the image or leave the editor. |
| Advertising and browsing information, potentially including IP address, browser/device information, page URLs, cookies or other ad identifiers, from browser interactions with Google AdSense. | Request, deliver, secure and measure advertisements, when Google ad code is allowed to load. | Google and its ad partners may receive this information. Some advertising disclosures can constitute “sharing” under California privacy law. Gridfunction does not sell visitor data lists. By default our ad code requests non-personalized ads. | Google and its partners determine their own retention periods under their policies; they are not controlled by this site. |
We do not ask you to create an account, provide a name, supply a payment method, or submit a precise location to use the generator. We do not operate our own analytics or advertising profiling database. Other features added in the future will require updates to this notice.
2. Advertising, cookies and third-party providers
Gridfunction has been configured for Google AdSense publisher ID pub-8109772726539850. Google ads appear only if the account and site are approved and Google actually fills an ad placement; there is no guarantee that an ad will appear. The website requests non-personalized advertising by default. Google may still use cookies or similar technologies for purposes such as ad frequency capping, reporting, security and fraud prevention; non-personalized does not mean no data processing.
Google may collect information and use it under the Google Privacy Policy. Cloudflare may handle technical data under the Cloudflare Privacy Policy. The site operator should also configure Google's Privacy & messaging tools for relevant jurisdictions, including its US state regulations and European regulations messages when applicable.
When you exercise Gridfunction's site-level advertising opt-out or activate a recognized GPC signal, our own code does not load the Google AdSense script on subsequent page loads in that browser. This does not remove information already processed by a provider. If advertising is blocked by your browser or not approved by Google, Google ads may not display.
3. California rights and your choices
Under the California Consumer Privacy Act as amended by the California Privacy Rights Act (CCPA/CPRA), and where the law applies, California residents may have the right to:
- Know and access categories and specific pieces of personal information collected about them.
- Request deletion or correction of qualifying personal information.
- Opt out of sale or sharing of personal information, including sharing for cross-context behavioral advertising.
- Limit certain uses of sensitive personal information where legally applicable.
- Exercise these rights without unlawful discrimination.
Do Not Sell or Share My Personal Information — manage your privacy choices. This preference can stop our site from requesting Google ads from your browser. We also respect GPC when made available to JavaScript by your browser. Changing this site's preference does not by itself delete historical data held by Google or Cloudflare.
We do not knowingly sell or share personal information of children under 16 without the authorization required by applicable law. The graph paper tool is intended for general audiences, and the site does not request a visitor's age.
4. Requests, verification and contact
To request access, correction, or deletion of personal information held by the site operator, or to raise a privacy concern, please contact the operator at the contact method published below. We may need to verify the request to avoid disclosing information to the wrong person. Because the editor has no user accounts or server-side database of paper designs, we normally cannot identify saved designs or images on individual devices.

5. Updates to this policy
We may update this policy if the tool, hosting, advertising services, legal requirements or our information practices change. The effective date at the top will be revised when material changes are made. Where required, we will provide appropriate notice before introducing new information uses.
