Terms of sale: Claude AC digital packs

These terms apply to the digital packs and printable guides sold in English on claude-ac.com: in US dollars, the US replacement pack, the AC & heat pump owner’s handbook, the hot upstairs workbook, the US homeowner library and the India buying pack; in euros, the European buyer’s pack and the European air-to-air heating guide. Everything else in the English sections (guides, state, city and country pages, calculators) is free. The guides sold in French have their own conditions générales de vente.

1. Who sells

The packs are sold by LACANGEL GROUP, SAS (simplified joint-stock company, France), SIREN 995 268 018 (RCS Paris), registered office 1 rue Marguerin, 75014 Paris, France, represented by its president Clément Lacaille. Contact: admin@tech-bharat.com. The website is published by Clem corp, Tech-Bharat brand (see the legal notice).

2. What you buy

Each pack is digital content: a web page you can read online, print or save as a PDF, with any file listed on its sales page (for the replacement pack, a spreadsheet), described on its sales page (contents, number of chapters, the free introduction and first chapter) before you buy. It is general information about the rules, programs and data of the market it covers (United States, European Union, India). It is not tax, legal, engineering or financial advice and does not promise any credit, rebate, subsidy, bill or price; Claude AC is not a tax preparer, an HVAC contractor or installer, a utility or a government agency.

3. Prices

Prices are in US dollars or in euros, as shown on each pack's page. The price shown is the total you pay: no tax, fee or delivery charge is added at checkout; euro prices include VAT. Your bank may apply its own currency-conversion fee if your card is in another currency (for example a card in rupees paying the India pack in US dollars).

4. Order and payment

You order from the pack's page and pay by card, Apple Pay, Google Pay or another method offered on Stripe's secure payment page. By paying, you accept these terms. The contract is formed when the payment is confirmed. Your bank statement shows “CLAUDE AC”. The Stripe page may display the name of the payment account, which is shared with other sites of the same seller; the seller is LACANGEL GROUP.

1-click purchases. When you pay for the US replacement pack, Stripe (not us) keeps the card you used, as the payment page states, so that your next purchases of the US packs on claude-ac.com can be made in one click. A 1-click button always shows the total in US dollars and the card it will use (for example “Visa •••• 4242”); clicking it places the order with an obligation to pay and charges that card right away, once, under these same terms (immediate access, refund policy). You can ask us at any time to delete the saved card, at the address in section 1.

5. Access

Access is immediate: after payment you are taken to your pack page. Bookmark it; the link stays valid and shows the latest version of the pack. If you lose it, write to us with the email address used for the payment and we will send it again. The pack is for your personal use: you may print it and fill it in, but not copy, share, resell or publish it.

6. Right to cancel

Consumers in the European Union and the United Kingdom normally have 14 days to cancel a distance contract. For digital content supplied immediately, this right is lost once access has started, if you asked for immediate access and acknowledged losing the right to cancel (French Consumer Code, article L221-28 13°; UK Consumer Contracts Regulations 2013, regulation 37). By paying, you make this request: the payment page says so just above the pay button.

7. Refund policy

To ask, email admin@tech-bharat.com with the email address used for the payment. Refunds go back to the card used, through Stripe; banks usually show them within 5 to 10 business days. Your statutory rights are not affected.

8. Complaints and disputes

Write first to admin@tech-bharat.com: we answer every message. Consumers in the European Union may also refer a dispute free of charge to the consumer mediator CM2C, 49 rue de Ponthieu, 75008 Paris, France (cm2c.net). These terms are governed by French law; if you are a consumer, you keep the protection of the mandatory rules of the country where you live and may bring a claim before its courts.

9. Personal data

Payment is processed by Stripe; we receive your name, email address, country and the payment status, never your card details. After a purchase, a purchase-recognition cookie (“fx1c”: a signed Stripe customer id, no card data, kept 13 months, never used for analytics or ads) lets you buy again in one click (section 4).
