Current storage position
This OnlineCalculator.xyz cookie policy is effective August 29, 2026. The site is operated by OnlineCalculator.xyz, 30 N Gould St Ste R, Sheridan, WY 82801, USA. Questions can be sent to support@onlinecalculator.xyz.
The application does not set cookies, localStorage, sessionStorage, IndexedDB records, advertising identifiers, analytics identifiers, or persistent calculation history. Directory phrases, filters, and calculator values remain in live page state. That position permits the focused tools to work without a cookie consent banner because no non-essential application storage is enabled.
The statement is about application behavior, not a claim that loading a website creates no network metadata. Hosting and browser features have separate data paths and are described independently.
Terms used on this page
A cookie is a browser-stored value returned with later requests to the relevant domain. It can support sign-in, preferences, security, measurement, or advertising. Persistent cookies outlive a browsing session; session cookies generally expire when a session ends.
Local storage, session storage, and IndexedDB are browser databases that can keep information without attaching it to every request. Cache storage and service workers can retain site resources. Pixels, scripts, and device signals can recognize activity without using a traditional cookie. This policy describes behavior broadly rather than relying on one technology name.
In-memory page state is temporary. A percentage input can remain visible while the page validates and calculates it, but the application does not write that value to a persistent browser store. Reset returns the form to its initial state.
Current storage category table
| Technology category | Current state | Product reason |
|---|---|---|
| Calculator-input cookies | Not used by application code | Numeric entries remain in live form state |
| Directory-query storage | Not used | Phrases and filters are matched locally and not remembered |
| Preference storage | Not used | No saved theme, precision, unit, or layout preference |
| Authentication cookies | Not used | No account or sign-in |
| Analytics identifiers | Not used | No third-party analytics vendor in the current service |
| Advertising identifiers | Not used | No advertising network or behavioral profile |
| Payment storage | Not used | No checkout or paid plan |
This table describes the current service. OnlineCalculator.xyz checks application storage, cookies, network requests, response headers, service workers, and host settings in a clean browser profile. If observed behavior differs, the settings or public policy will be corrected.
Browser-controlled restoration
A browser may offer form autofill, restore a page from the back-forward cache, retain downloaded site resources, or synchronize browsing history according to the user’s browser account and settings. Extensions can observe or modify pages under permissions granted by the visitor. Those behaviors are not a calculator account or operator database.
Use the page reset control and browser site-data settings when needed. Clearing browser storage cannot delete an email already sent or hosting logs already processed. Conversely, emailing support cannot recover a calculator entry that remained local.
Hosting security
Vercel is the planned host. Hosting and network systems process ordinary requests as described by the Privacy Policy. A public static page should not require an OnlineCalculator.xyz application cookie, but a specific hosting, preview, load-balancing, or abuse-prevention configuration can introduce a necessary cookie or comparable mechanism.
If an essential technology sets storage on the public service, this policy will name it, its provider, purpose, first- or third-party status, and duration. It will not be hidden inside an undefined “strictly necessary” category.
Why history is absent
A saved calculator history might appear convenient, yet it changes data responsibilities. A list of values can reveal education, work, purchases, or projects once associated with a device or identity. The site uses a copyable result and a clean reset rather than automatic persistence.
For a practical test, enter 15 and 80 in the percentage tool and obtain 12 as the part. Reloading the page should not restore those two values from site-controlled persistent storage. If it does, report the route and storage evidence because the observed behavior, purpose, controls, and this policy must agree.
External destinations and email
Selecting the support link opens the visitor’s mail environment. Mail providers can use their own cookies and signed-in sessions. Following a clearly labeled external link leaves OnlineCalculator.xyz and enters a separate policy environment. The pages do not embed video players, social widgets, maps, ads, remote document viewers, or comment systems.
Third-party embeds can transmit requests before a visitor intentionally follows a link. Adding one requires privacy, storage, performance, and consent review rather than treating it as ordinary page decoration.
Future changes
A future preference, saved set, account, analytics system, or paid feature is not promised. Before any storage is activated, the operator must document the fields, purpose, provider, duration, access, deletion, security, and applicable legal basis. Non-essential technology must remain off until a required choice is obtained.
Where consent applies, rejection must be as clear as acceptance and the calculators must not be conditioned on unrelated tracking. Prior consent cannot be stretched to a materially different purpose. A policy revision will show a new effective date.
Frequently asked questions
Will the site remember my precision setting?
No. The service has no persistent preference storage. Defaults return with a new page lifecycle.
Why might an old value reappear anyway?
Browser autofill or back-forward restoration can re-display a field under browser control. Reset the page and review browser settings.
Are analytics cookies used?
The current service has no third-party analytics vendor or analytics identifier. OnlineCalculator.xyz periodically checks network and storage behavior and updates this disclosure if that changes.
What if a cookie is added later?
Its purpose and duration must be documented, both policies updated, and any required control or consent implemented before activation.
