Periodic Calendar VS https://alanaknows.com/

• Open Source
  Periodic Calendar is open source, which means it is free to use and its source code can be modified and improved by users, fostering community development and collaboration.
• Cross-platform Compatibility
  The software is designed to work on multiple operating systems including Linux, which broadens accessibility and usability for a diverse user base.
• Feature-rich
  Periodic Calendar offers a range of features for managing and tracking menstrual cycles, including visual charts, graphs, and reminders, which can be beneficial for health tracking.
• User Privacy
  As a locally hosted application, it provides better control over personal data and privacy compared to cloud-based applications.

Possible disadvantages

• Limited Support and Updates
  Being a community-driven project, it may not receive regular updates or prompt support compared to commercial software, potentially leading to compatibility issues or unresolved bugs over time.
• User Interface
  The interface might be less polished or user-friendly compared to modern commercial applications, which can affect user experience and ease of use.
• Learning Curve
  Users unfamiliar with open-source applications or those who are not technologically savvy may find it challenging to set up and use efficiently.
• Linux-focused
  While it is cross-platform, the primary focus is on Linux, which might result in sub-optimal performance or features on other operating systems.

• Domain still registered
  The domain alanaknows.com is still owned and registered, meaning the owner has the option to reactivate or rebuild the site in the future rather than losing the domain entirely.
• Placeholder prevents dead link errors
  Instead of showing a generic browser error (like a DNS failure), the hosting provider displays a suspended page notice, which can be less confusing to visitors than a broken connection.
• Potential for future content
  Since the domain is intact, if the account issue is resolved, the original website content could potentially be restored without needing to re-register the domain.
• Clear indication of status
  The suspended page URL (cgi-sys/suspendedpage.cgi) clearly signals that this is a hosting-related suspension rather than the site being permanently deleted, which can help users or search engines understand the temporary nature of the outage.
• No malicious content risk
  Because the site is suspended and not actively serving custom content, there is no current risk of the site hosting malware, spam, or other harmful material that active but neglected sites might accumulate.

Possible disadvantages

• Website is completely inaccessible
  The main URL redirects to a suspended page, meaning visitors cannot access any actual content, information, or services that the site was intended to provide.
• Unprofessional appearance
  A suspended page gives a poor impression to visitors, potential clients, or collaborators, suggesting neglect, financial issues, or abandonment of the site or associated business/brand.
• Loss of SEO and traffic value
  Prolonged suspension can hurt search engine rankings and any previously built organic traffic, as search engines may de-index the site or lower its authority due to inaccessibility.
• Unknown cause of suspension
  The suspension could be due to unpaid hosting bills, terms of service violations, or technical issues, and without more context, users or stakeholders cannot know the severity or how soon it might be resolved.
• No information available
  Since the site is suspended, there is no way to evaluate the actual content, design, functionality, or purpose of the original website, making it impossible to assess its value or quality.

• has anyone seen an uptick on period and ovulation trackers on facebook like wtf

  Well there is but I don't know if I'd trust it, frankly. Periodic Calendar. Open source and licensed under the GPLv3. Thing is I don't think it's maintained anymore; the most recent version was released 7 years ago, and the most recent... Source: over 4 years ago
