Privacy Policy
Last reviewed: this page describes how the converter works today. It contains placeholders marked [OWNER: …] that the site owner must complete, and it should be reviewed by a qualified adviser before you rely on it for any legal purpose. It is not a guarantee of compliance with any specific law.
The short version
This tool converts dates between the Gregorian (Miladi) calendar and the Iranian Solar Hijri (Shamsi / Jalali) calendar. The conversion happens entirely inside your own web browser. There is no account to create, no server that receives your dates, and no network request is made to perform a conversion. By default the converter sets no cookies and makes no third-party requests.
The one nuance worth stating plainly: optional advertising and analytics layers are available but are off by default. They only run if the site owner switches them on and you give consent. If that ever happens, third-party providers may set cookies and process some data. The rest of this page explains all of that in detail.
Who is responsible for your data
The data controller for this site is [OWNER: legal name of the site operator]. For any privacy question or request you can contact [OWNER: contact email address], or use the details on our contact page.
What the converter does on your device
When you type or paste a date, the app uses a well-tested arithmetic conversion routine running locally in your browser and cross-checks the result against your browser's own Persian calendar. Your input never leaves the device for the purpose of conversion. Because the tool uses a date-only model with no timestamps, your time zone does not shift the result.
What is stored on your device
The converter uses your browser's localStorage only to remember your own preferences, so the app feels the same next time you open it. This data stays on your device and is not transmitted to us. It includes:
- Theme — whether you chose light or dark mode.
- Digit preference — whether numbers display as Persian or Latin digits.
- Consent record — if consent prompts are shown, your choice about optional ads and analytics is recorded locally so you are not asked repeatedly.
You can clear this at any time by clearing your browser's site data for this site. Doing so simply resets the converter to its defaults.
Optional advertising and analytics
Advertising (Google AdSense) and analytics are optional layers that are disabled by default. They activate only when the site owner has configured them with real credentials, the build is a production build, you are online, and you have given consent. If, and only if, both conditions are met:
- Third-party scripts from the relevant provider may load.
- Those providers may set their own cookies and process data such as your IP address, device and browser information, and interactions, in line with their own policies and the choices you make in any consent prompt.
- For personalised advertising in the UK, EEA, or Switzerland, a Google-certified consent mechanism would additionally be required before ads run.
The specific vendors, where used, are [OWNER: name the ad and analytics providers actually enabled, e.g. Google AdSense, and the consent mechanism used]. The detail of which cookies are set and why is explained on our cookies page. We do not claim "no data is ever collected" — when these layers are enabled, the converter itself still collects nothing, but the third-party providers process data as described above.
Your rights
Depending on where you live, you may have rights over personal data, including the right to access it, correct it, delete it, restrict or object to its processing, and to withdraw consent at any time. Because the converter itself collects no personal data, most requests will relate to any optional third-party layers that are enabled. To exercise a right, or to ask how a request would be handled, contact [OWNER: contact email address]. You may also have the right to complain to your local data protection authority.
Children
This is a general-purpose utility and is not directed at children. It does not knowingly collect personal data from anyone.
Changes to this policy
If the way the site handles data changes — for example, if optional ads or analytics are turned on — this page and the cookies page will be updated to reflect that. Please check back from time to time.
