Your data stays
on your device
How Drivenly.xyz handles information, cookies, analytics, and advertising — explained plainly, with no fine-print surprises.
The short version
Drivenly.xyz ("Drivenly," "we," "us," or "our") operates the website drivenly.xyz, a free pregnancy due date calculator and informational resource. This Privacy Policy explains what information our site interacts with, how it's used, and what choices you have.
The short version: the dates and numbers you enter into our calculator are processed in your browser and are never transmitted to or stored on our servers. We do not require sign-up, we do not build user profiles, and we do not sell personal information.
The rest of this policy covers the limited data that does get collected — primarily through cookies, analytics, and advertising — and explains your rights and choices regarding that data.
What happens to the dates you enter
When you use the Drivenly pregnancy due date calculator, you may enter information such as the first day of your last menstrual period, an estimated conception date, or an ultrasound date. This information is processed entirely within your browser using client-side JavaScript.
- We do not transmit this information to our servers.
- We do not store this information in any database.
- We do not associate this information with your identity, IP address, or device.
- Closing or refreshing the page clears any values you entered.
Because this data never reaches us, we have no ability to access, retrieve, or share the specific dates or results you calculate.
How we use cookies and similar technologies
Cookies are small text files stored on your device that help websites remember information about your visit. Drivenly.xyz uses cookies in the following ways:
Google Analytics
We may use Google Analytics, with your consent where required by law, to understand general traffic patterns — such as which pages are visited and how long visitors stay. Google Analytics uses cookies to collect this information, which is processed in aggregate and is not used to identify you personally. You can learn more about how Google handles this data through Google's own privacy documentation.
Advertising cookies
We use Google AdSense to display ads, which relies on its own cookies and similar technologies. See the Advertising section below for details.
Managing cookies
Most browsers let you block or delete cookies through their settings. Blocking cookies may affect how ads are displayed but will not prevent the calculator itself from functioning, since calculator results don't depend on cookies at all.
Google AdSense & DoubleClick
Drivenly.xyz displays advertisements served by Google AdSense, which may use the DoubleClick cookie and other technologies to serve ads based on a visitor's prior visits to this and other websites.
- Google uses cookies (including the DoubleClick cookie) to serve ads based on your visits to this site and other sites on the internet.
- You may opt out of personalized advertising by visiting Google's Ads Settings.
- Third-party vendors, including Google, may use cookies to serve ads based on someone's prior visits to our website or other websites.
- We do not select, vet, or control the specific ads shown to any individual visitor — ad placement and targeting is handled automatically by Google's systems.
For more information about how Google uses information from sites that use its services, visit Google's Partner Sites policy.
Links to other websites
Drivenly.xyz may contain links to third-party websites, including healthcare resources, government health agencies, or informational sources we cite in our content. We are not responsible for the privacy practices or content of those external sites. We encourage you to review the privacy policy of any third-party site before providing it with personal information.
COPPA compliance
Drivenly.xyz is not directed at children under the age of 13, and we do not knowingly collect personal information from children under 13, in compliance with the Children's Online Privacy Protection Act (COPPA). Our content concerns pregnancy and is intended for an adult audience. If you believe a child under 13 has provided us with personal information, please contact us at legal@drivenly.xyz so we can address it.
Your rights under the CCPA
If you are a California resident, the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA), gives you certain rights regarding personal information collected by businesses.
| Right | What it means |
|---|---|
| Right to know | Request disclosure of the categories of personal information we collect and how it's used. |
| Right to delete | Request deletion of personal information we hold about you, subject to certain exceptions. |
| Right to opt out | Opt out of the "sale" or "sharing" of personal information, including for cross-context advertising. |
| Right to non-discrimination | We will not deny services or charge different prices for exercising your privacy rights. |
Because we do not collect calculator data and minimize the personal information we process, our footprint under the CCPA is limited primarily to analytics and advertising cookies described above. To exercise any of these rights, contact us at legal@drivenly.xyz.
How we protect what little data exists
Because calculator inputs are processed client-side and never reach our servers, the primary data security consideration on Drivenly.xyz relates to the limited analytics and advertising data described above, which is handled by Google's infrastructure under its own security standards. We serve our site over HTTPS to protect data in transit between your browser and our hosting provider.
What you can control
- Use the calculator without entering any identifying information — it only needs dates.
- Block or clear cookies at any time through your browser settings.
- Opt out of personalized advertising through Google's Ads Settings, linked above.
- Decline non-essential analytics cookies where a consent option is presented.
- Contact us with any privacy question or correction request at any time.
How we handle updates to this policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or for other operational reasons. The "Last Updated" date at the top of this page reflects the most recent revision. We encourage you to review this page periodically.
