Cookie Policy
Effective date: Jun 04, 2026
At Precise Calcs (“we”, “us”, or “our”), we use cookies and similar tracking technologies to enhance your experience, analyze site usage, and ensure our calculators work properly. This Cookie Policy explains what cookies are, which ones we use, and how you can control them.
What Are Cookies?
Cookies are small text files stored on your device (computer, tablet, or phone) when you visit a website. They help the website remember your actions and preferences over time, such as your chosen units or decimal precision.
How We Use Cookies
We use only minimal, privacy‑respecting cookies. They fall into these categories:
1. Strictly Necessary Cookies (Essential)
These cookies are required for the site to function. You cannot opt out of them because the site would break. Examples:
- Remembering your calculator inputs temporarily (e.g., which tab you selected) during a single session.
- Maintaining security and load balancing.
These cookies do not store any personally identifiable information.
2. Preference / Functional Cookies
If you choose to set a default decimal precision (e.g., 2 decimal places) or a preferred unit system (metric/imperial), a cookie can remember that for your next visit. These are optional. If you decline, you’ll just need to set your preferences each time.
3. Analytics Cookies (Performance)
We use Google Analytics to understand how visitors interact with our calculators – which tools are most popular, how long users stay, and if any errors occur. This helps us improve Precise Calcs.
- Google Analytics uses first‑party cookies that anonymize your IP address.
- Data is aggregated and never sold.
You can opt out of analytics cookies (see “How to Control Cookies” below).
4. Advertising Cookies (if applicable)
We currently do not run ads. If we introduce non‑intrusive ads in the future, this policy will be updated, and you will be given a clear opt‑out option.
Cookies We Use – Specific List
Here are the typical cookies you may find on Precise Calcs:
| Cookie Name | Purpose | Duration | Type |
|---|---|---|---|
precise_prefs | Stores your preferred decimal places / units | 1 year | Preference |
precise_session | Temporary session ID (essential for multi‑step calculators) | Session (closed when you quit browser) | Necessary |
_ga | Google Analytics – distinguishes unique users | 2 years | Analytics |
_gid | Google Analytics – distinguishes users within a day | 24 hours | Analytics |
_gat_UA-* | Google Analytics – throttles request rate | 1 minute | Analytics |
Note: Actual cookie names may vary slightly. You can inspect cookies via your browser’s developer tools.
How to Control and Delete Cookies
You have full control over cookies. Most browsers allow you to:
- See what cookies are stored and delete them individually.
- Block third‑party cookies entirely.
- Block all cookies (though some site features may break).
Opting out of Google Analytics
You can prevent Google Analytics from using your data by:
- Installing the Google Analytics Opt‑out Browser Add‑on.
- Or, simply disabling analytics cookies in your browser settings.

Third‑Party Cookies
We do not intentionally embed third‑party cookies except for Google Analytics. However, if we later add social sharing buttons or embedded videos, those services may set their own cookies. We will update this policy accordingly.
Consent
When you first visit Precise Calcs, you will see a simple cookie banner asking for your consent to set non‑essential (analytics/preference) cookies. Your choices are:
- Accept all – enables analytics and preference cookies.
- Essential only – blocks analytics and preference cookies; calculators still work.
- Manage preferences – fine‑tune which categories you allow.
You can change your mind at any time by clicking the “Cookie Settings” link in the footer.
Changes to This Cookie Policy
We may update this policy occasionally (e.g., if we add new calculators that require a different cookie). The “Effective date” at the top will reflect the latest version. Your continued use of Precise Calcs after changes means you accept the updated policy.
