Privacy Policy

Google advertising, cookies and your choices

PeriodlyWise may support the site through Google AdSense. These disclosures apply when Google ads are enabled; a publisher-verification tag or ads.txt entry does not itself activate advertising.

Advertising technologies and third parties

When Google ads are enabled, Google and other advertising vendors may store or read cookies and use web beacons, IP addresses and device or browser identifiers to deliver ads, measure performance and prevent fraud.

Where personalization is permitted by your consent, settings and applicable requirements, Google and its partners can use advertising cookies to tailor ads using visits to PeriodlyWise and other websites. Ad requests can also disclose the page URL and technical information about your browser or device.

Other vendors or advertising networks participating in ad delivery may use their own technologies. Where a consent message is displayed, its partner list identifies participating providers and links to their information and privacy policies.

Advertising privacy and opt-out links

• Google Ads Settings: manage or turn off personalized advertising
• How Google uses information from partner sites and apps
• WebChoices: opt out of interest-based ads from participating companies

These choices do not remove every ad or necessarily stop processing needed for delivery, measurement or fraud prevention. Some preferences are browser- or device-specific. Google account ad settings do not replace your choices in a site's consent message.

Consent and changing your choices

For visitors in the European Economic Area, the United Kingdom and Switzerland, personalized Google ads require consent collected through a Google-certified consent management platform. Where a consent message is displayed, use it to accept, decline or manage vendors and purposes. You can revisit or withdraw consent through the privacy-settings or consent-revocation link provided with that message. Essential sign-in and security storage is separate from advertising consent.

Current analytics preferences

Optional Google Analytics and Microsoft Clarity, including session recordings and interaction insights, stay blocked until you explicitly allow analytics. Rejecting optional analytics does not prevent the core tracker or sign-in services from working. Your choice is stored in this browser for 180 days. Revisit Your privacy choices to change it. Turning analytics off reloads open PeriodlyWise tabs to stop measurement and removes accessible first-party analytics cookies; save unfinished entries first. Browser or vendor controls may be needed for cookies on other domains. This first-party analytics choice does not grant advertising consent or replace a Google-certified advertising CMP.

A first-party Cloudflare endpoint selects regional privacy controls using approximate connection country and browser privacy signals, without requesting GPS or returning your IP address to the page. In the EEA, UK and Switzerland, Google's published consent manager handles available regional choices; a previous analytics refusal is preserved until a new explicit choice. If Google's analytics mapping is unavailable, analytics stays off; if analytics is not configured in that manager, our separate explicit analytics choice remains necessary. In the US, Google's applicable state opt-out controls are available separately; opting out here also disables optional analytics. India and other locations continue to require analytics opt-in. Global Privacy Control disables optional analytics. Essential tracker and account services are unaffected. Loading a consent manager does not activate ads.

Private cycle information

We do not use private tracker entries, saved cycle records or health notes to personalize advertising. The analytics loader is disabled on private account and password-recovery pages and on URLs containing recognized sensitive parameters. Account and personal cycle-result sections are marked for Clarity masking. Avoid sharing sensitive health information in forms or messages supplied by advertisers.

1. Information you provide

PeriodlyWise may collect information you choose to enter or save, including period start dates, period length, cycle length, cycle regularity, flow details if available, notes if you choose to add them, saved period records, generated estimates and reports, account details such as name and email address, and authentication method.

You should only enter information you are comfortable using with PeriodlyWise.

2. Information created by our tools

When you use PeriodlyWise, our tools may generate information from the details you enter, such as estimated next period date, possible period window, estimated ovulation window, estimated fertile window, cycle confidence ranges, irregular-cycle summaries, projected future period windows, and downloadable or printable summaries.

The Pregnancy Calculator processes your entries in your browser. If you sign in and select Save Record, we store the estimate, the dating details used to calculate it, and any note you choose to add. You can edit, download or delete a saved estimate from the calculator.

These outputs are created to provide the tool experience. They are not medical records or clinical documents. For health-related limitations, please read our Medical Disclaimer.

3. Account information

If you create an account or sign in, PeriodlyWise may process account-related information such as name, email address, login provider, account identifier, saved profile details, saved cycle records, and session information.

If you use Google sign-in, Google may process information according to its own terms and privacy practices. PeriodlyWise does not control Google's systems.

4. Local storage

Some PeriodlyWise features may use browser local storage to keep tracker inputs or temporary settings on your device. Local storage may be affected if you clear browser data, use private browsing, change devices, change browsers, disable storage, use privacy extensions, or reset your device.

Local storage is different from account-based storage. If information is stored locally, it may not be available on another device or browser.

5. How we use information

PeriodlyWise may use information to operate the period, ovulation, fertility-window, and irregular-cycle tools; calculate estimates and ranges; save records when you choose to sign in; show account-based cycle history; generate summaries, reports, or reminders; improve the user experience; maintain site security; troubleshoot technical issues; prevent misuse; and comply with applicable legal requirements.

We do not use cycle information to provide medical advice, diagnosis, fertility treatment, contraception guidance, or emergency guidance.

6. Authentication and service providers

PeriodlyWise relies on service providers for hosting, security, account functionality, database infrastructure, optional Google sign-in and email delivery. Google Analytics and Microsoft Clarity provide optional analytics only after your analytics consent.

Service providers may process limited information as needed to provide their services. Their own policies may also apply.

7. Cookies, analytics, and similar technologies

Essential cookies, local storage and session storage support the website, account sessions, preferences and security. Optional Google Analytics and Microsoft Clarity remain blocked until analytics consent and stop after rejection or withdrawal. Your analytics choice does not grant advertising consent.

The tracking loader is disabled on private account and password-recovery pages and on URLs containing recognized sensitive parameters. Account and personal cycle-result sections are marked for Clarity masking. You can change your analytics choice through the footer privacy link without losing access to essential services.

8. Advertising and affiliate links

PeriodlyWise may display advertising, sponsored content, affiliate links, or promotional placements in the future, including, but not limited to, Google Ads and Google AdSense. If advertising or affiliate links are used, third-party partners, including, but not limited to, Google, may process certain technical or interaction data according to their own privacy practices.

Advertising does not mean PeriodlyWise shares your private cycle records directly with advertisers.

9. Sensitive information

Cycle-related information can be personal and sensitive. PeriodlyWise aims to collect only what is needed for the tools to work. You should avoid entering unnecessary sensitive details in free-text notes. If you choose to add notes, you are responsible for what you write.

10. Sharing of information

PeriodlyWise may share information only when reasonably necessary, such as with service providers that help operate the site, when required by law or legal process, to protect the rights, safety, or security of PeriodlyWise, users, or others, during a business transfer, merger, acquisition, or similar event, or with your direction, such as when you export, copy, print, or share a report.

PeriodlyWise does not sell private cycle records as a product.

11. Data retention

PeriodlyWise may keep information for as long as needed to provide the tools and account features, maintain saved history, comply with legal obligations, resolve disputes, prevent misuse, and improve reliability and security.

If you delete records or clear local data, some information may be removed from the active tool experience. Backups, logs, or service-provider records may take longer to expire.

12. Your choices

Depending on the feature, you may be able to use the basic Period Tracker without an account, choose not to save records, delete saved records, clear local browser data, sign out, avoid free-text notes, avoid optional tracking fields, use or avoid Google sign-in, or request account or data deletion when such support is available.

13. Security

PeriodlyWise aims to use reasonable technical and organizational measures to protect information. However, no website, database, account system, browser storage method, or internet transmission is completely secure.

You are responsible for keeping your account credentials secure and using trusted devices when entering sensitive information.

14. International users

PeriodlyWise may be accessed from different countries. Data may be processed through infrastructure or service providers located in different jurisdictions. By using PeriodlyWise, you understand that information may be processed according to the systems and providers used to operate the website.

15. Children and minors

PeriodlyWise is not intended for children who cannot legally consent to use online services in their location. If a minor uses PeriodlyWise, they should do so with involvement and permission from a parent or legal guardian.

16. Changes to this Privacy Policy

PeriodlyWise may update this Privacy Policy from time to time. Updates may reflect changes in our tools, account features, storage practices, analytics, advertising, legal requirements, or service providers. The Last updated date shows when this Privacy Policy was most recently revised.
