Privacy & data choices

What stays in your browser

Calculations run on your device. Plans, measurements, baselines, and results are not uploaded to an application server.

The browser holds up to three small items in localStorage, which is unencrypted and visible to others using the same browser profile. Saved plans are stored under motorcycle-ergonomics:saved:v1, only when you press Save. Your analytics choice is stored as site-analytics-consent. If you withdraw ad consent, that choice is stored as site-ads-consent. Delete a plan in Saved plans, or clear this site's data in your browser to remove them all.

Downloaded exports are separate files that you manage.

Share links

Share setup places only the current measurements in the URL fragment. Baselines and saved-plan names are excluded. Anyone with the full link can read those fields, so do not share a link that holds information you want private. Plan files (JSON) hold the entire plan.

Analytics

Optional Google Analytics 4 loads only after a separate analytics opt-in. It receives pseudonymous page_view, tool_start, tool_complete, preset_select (style name), share_setup, save_plan, export_plan, export (file format), guide_to_tool, outbound_click (host only), and scroll_75 events. Page views include the current and referring page URLs with query strings and fragments removed; inputs, exports, and free text are not sent. Do Not Track and Global Privacy Control suppress analytics, and the footer privacy control can revoke consent.

If you allow analytics, Google Analytics sets cookies whose names start with _ga (_ga and _ga_ followed by the property identifier) to tell visits apart. The analytics configuration turns off Google signals and ad personalization signals. Declining or withdrawing consent deletes the _ga cookies this site can reach.

Advertising

Google AdSense provides the advertising on this site. To let you choose, pages that can show ads load Google's consent manager and the Google AdSense script when they open, which sends your IP address, browser details and the page address to Google; the AdSense script is held paused and makes no ad requests until Google's consent manager answers. Where consent is required, that means until you allow ads. Elsewhere ads can load without a prompt, and this site then asks Google for non-personalized ads.

When Global Privacy Control or Do Not Track is on, ads are not requested, and the consent manager and AdSense script are not loaded.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other sites.

Manage this in Google Ad Settings, opt out of vendor ad personalization at optout.aboutads.info, or read how Google uses data from sites that use its services.

Hosting

The site is hosted on Cloudflare Pages, so page and asset requests reach Cloudflare. Hosting providers can log normal request data such as IP addresses under their own policies. Source links lead to external websites with their own policies.

Change or withdraw consent

The first visit shows an analytics choice banner, and analytics stays off until you allow it. Where consent is required, ads load only after you allow them, and Google's consent provider stores its own record of your choice. Global Privacy Control or Do Not Track keeps ads and analytics off.

On pages that show ads, select Ad privacy choices in the footer at any time. It withdraws ad consent, asks Google's consent manager to reopen its choices, turns analytics off until you allow it again, and opens the analytics preferences.

Your rights and contact

Depending on where you live, you may have rights to access, correct, delete, or object to the use of personal data. This site has no accounts and does not receive your plans or measurements. For data held by Google or Cloudflare, use their own privacy tools.

Email privacy requests to dheerajnamburu@gmail.com. Do not send private files or sensitive personal information.

Children

This site is not directed to children, and the operator does not knowingly collect personal information from children.
