Terms of service and conditions for using Holiday Optimizer

Last updated: February 7, 2026

👋 About this project

Holiday Optimizer is an independent project built and maintained by Waqar Bin Kalim to help people plan time off more easily. These terms outline the guidelines that help keep things clear and fair for everyone.

It's a side project intended for personal planning, not professional advice. Please verify dates and policies with official sources before making decisions.

Built with modern tools (including AI assistance) and supported on a best-effort basis.

🤖 AI-Generated Content

Blog articles and other content on this site may be created with the assistance of AI tools. AI-generated content may contain errors, outdated information, or inaccuracies.

Please verify all information independently before making travel plans, booking time off, or relying on any dates, facts, or recommendations presented in our articles.

💰 Affiliate Disclosure

Some links on this site may be affiliate links. If you make a purchase through these links, the maintainer may earn a commission at no additional cost to you. This helps support the ongoing development and maintenance of Holiday Optimizer.

Affiliate partnerships include Travelpayouts for travel-related services. These relationships do not influence the recommendations or content provided.

🎯 Service Overview

Holiday Optimizer analyzes holidays, weekends, and company days off using bundled holiday data (from the date-holidays library) and your inputs to suggest PTO combinations that maximize time off.

This plan is a helpful draft. Feel free to tweak it to match your preferences.

Note: Service availability depends on the application and the freshness of the bundled data. While reliability is prioritized, occasional maintenance or updates may temporarily affect functionality.

🤝 Terms of Use

By using Holiday Optimizer, you agree to:

  • Use the service for personal holiday planning purposes
  • Verify dates and policies with official sources before making decisions
  • Understand holiday data is generated from bundled datasets and may lag official updates
  • Respect the system's security and integrity
  • Do not copy, redistribute, or commercialize the service or its outputs
  • Accept that features and functionality may evolve over time
  • Take responsibility for decisions made based on the tool's outputs

💳 Paid Calendar Export & Polar Checkout

  • Payments: The optional “Save as Calendar (.ics)” feature is processed by Polar via Checkout. Polar collects the billing details (email, address, payment method) needed to complete the transaction, including billing address where required, and confirms the purchase back to the service. See their Privacy Policy for details.
  • Availability: The calendar export is available to users globally.
  • File retention: Once generated, the ICS file is stored in a private AWS S3 bucket under a random token and deleted automatically after a short retention window (typically about 48 hours). Download links provided via the site are valid for the same window and are intended for your personal use only.
  • Pre-checkout validation: To ensure the export works, the service generates a temporary calendar file before checkout as a preflight check. The download link is only issued after Polar confirms payment.
  • Data deletion: The maintainer can delete data they control (like export files and download tokens). Billing details are stored by Polar. At your request, the maintainer can delete Polar Customer objects when possible, but Polar may still retain certain records for legal or compliance reasons. You can also contact Polar support directly. For details on how Polar handles retention or deletion, refer to their Privacy Policy and Services Agreement.

↩️ Refunds & Delivery Issues

The calendar export is delivered instantly as a digital file, so all sales are final and non-refundable once the download link is issued. Exceptions are rare and handled case-by-case for billing errors or delivery failures as noted below.

  • Download issues: If you cannot access the download link on the thanks page, a replacement link may be issued once for the same order after basic verification. Report delivery issues promptly (requests made after 30 days may not be processed).
  • Expired links: Download links typically expire within ~48 hours. If the original link expires, a new purchase may be required; re-issuance after expiry is at the maintainer's sole discretion.
  • Billing issues: If you see a duplicate charge for the same plan or a genuine unauthorized transaction, contact support first. The maintainer can review and may issue a refund at their sole discretion or direct you to Polar support for resolution.
  • Chargebacks: Please contact the maintainer before filing a chargeback so issues can be resolved quickly if possible.
  • Timing: Responses and any discretionary resolutions are provided on a best-effort basis and are not guaranteed within a specific timeframe.
  • Cooling-off waiver: By purchasing, you request immediate access to the digital download and waive any statutory cooling-off/withdrawal period for digital goods.

Please reach out via email (see Contact & Support) before filing a chargeback so issues can be reviewed directly; unsupported or late claims may be declined.

💾 Data & Privacy Summary

Plans and preferences are stored locally in your browser. Holiday calculations run locally using bundled date-holidays data, and the app uses limited, consent-based analytics to understand usage and improve the product.

For full details, review the Privacy Policy.

⚠️ Limitations & Accuracy

Holiday Optimizer is a small side project provided “as is” and “available” without warranties of any kind, whether express or implied, including but not limited to accuracy, reliability, fitness for a particular purpose, or non-infringement. The maintainer does their best, but this is a personal project and you're responsible for how you use it.

Blog articles, travel recommendations, prices, dates, and other content on this site are generated with AI assistance and may be inaccurate, outdated, or incomplete. You assume full responsibility for independently verifying any information before acting on it. Prices, availability, visa requirements, safety conditions, and local regulations change frequently—always confirm details with official sources before booking travel or making plans.

In no event shall the maintainer be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the service or reliance on its content, including but not limited to travel disruptions, financial loss, or missed bookings. The maintainer is also not responsible for outages or third-party changes. To the extent permitted by applicable law, total liability is limited to the amount you paid to use the service (if any).

Since I'm based in Ontario, Canada, these terms are governed by the laws of the Province of Ontario. Any disputes would be handled by the courts in Ontario.

Always double-check important dates with official calendars or your employer.

🔄 Updates & Modifications

As an evolving project, Holiday Optimizer may undergo periodic updates and improvements. The right to modify or update these terms and the service's functionality is reserved. Users are encouraged to periodically review these terms for any changes.

📬 Contact & Support

This is a personal side project without a dedicated support team. The maintainer only works on it in personal time, so issues and feature requests are handled on a best-effort basis.

For billing, delivery, or refund-related questions, please email (best effort, responses are not guaranteed):

Response times and updates may be delayed and are not guaranteed.
