Terms of Service

By using PerGram (“the Service”), you agree to the following terms. If you do not agree, please do not use the site.

Service Description

PerGram is a free price comparison tool for dietary supplements. We aggregate publicly available pricing, ingredient, and supplement facts data from retailer websites and normalize it to cost-per-gram and cost-per-serving metrics. The Service is provided for informational purposes only and is not a substitute for professional medical, nutritional, or financial advice.

Pricing Accuracy

Prices displayed on PerGram are sourced from retailer websites and updated regularly through automated scraping. However:

  • Prices may change between the time we last checked and the time you visit a retailer's website. Always verify the final price at checkout.
  • We do not guarantee the accuracy, completeness, or timeliness of any pricing data. Retailer promotions, coupons, shipping costs, and taxes are not reflected in our comparisons.
  • Supplement facts data (ingredients, serving sizes, potency) is extracted from product labels and retailer listings. While we use multiple extraction methods and quality checks, errors may occur.

Affiliate Links

PerGram contains affiliate links to retailer websites. When you click these links and make a purchase, we may earn a commission at no additional cost to you. Affiliate relationships do not influence product rankings, which are determined solely by normalized pricing data. For full details, see our Affiliate Disclosure.

No Health Claims

  • PerGram does not make claims about the efficacy, safety, or health benefits of any supplement product.
  • The information on PerGram is not intended to diagnose, treat, cure, or prevent any disease. Consult a qualified healthcare provider before starting any supplement regimen.
  • Product categorization and formulation labels are provided for comparison convenience and do not constitute medical or nutritional endorsements.

Acceptable Use

You agree not to:

  • Scrape, crawl, or systematically download data from PerGram for commercial purposes without prior written permission.
  • Attempt to interfere with the operation of the Service, including overloading servers or exploiting vulnerabilities.
  • Use the Service to mislead consumers or misrepresent pricing data sourced from PerGram.
  • Submit false or misleading bug reports, feedback, or other user-generated content.

Limitation of Liability

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED. TO THE FULLEST EXTENT PERMITTED BY LAW:

  • PerGram shall not be liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of or inability to use the Service.
  • PerGram shall not be liable for any purchasing decisions you make based on data displayed on the site, including incorrect prices, inaccurate supplement facts, or missing product information.
  • PerGram is not responsible for the content, products, services, or practices of any third-party retailer websites linked from the Service.

The PerGram name, logo, and original site content (including the normalization methodology, UI design, and editorial text) are the property of PerGram. Product names, brand names, images, and trademarks displayed on the site belong to their respective owners and are used for identification and comparison purposes only.
