Privacy

Your email address

PayPal passes us the email address on your account when you check out. We use it for three things: sending the download link, sending the receipt, and replying if you write to us.

We do not add you to a mailing list because you bought a book. If a newsletter ever exists you will have to ask for it, and you will be able to leave in one click.

The payment

PayPal tells us that a payment of $7.99 succeeded, gives us a transaction reference, and tells us which country it came from. That is everything we get.

We never see your card number, your bank details or your PayPal password, and we have no way to charge you a second time. PayPal is the party handling the payment, under its own privacy terms.

The download record

When the file is fetched, our server notes the time, the IP address that asked for it, and which version of the file went out.

That exists for two reasons, both dull. The first is proof of delivery: if a payment is questioned weeks later, this record is how we show the book actually arrived. The second is fraud — one link being pulled two hundred times from forty countries is a link that has been passed around, and we would like to be able to see that happening.

Emails you send us

If you write to us about an order, we keep the thread while we sort it out and for a while after, so that a second message about the same problem still makes sense.

How long things are kept

Order and payment record

As long as tax and accounting rules require, which in most places is around seven years.

Download log

About twelve months, then deleted. Long enough to outlast any dispute window.

Support emails

About twenty-four months.

Anything else

There is nothing else. We do not build a profile of you.

Who else sees it

Only the parties delivery needs: PayPal to take the payment, an email provider to carry the message, and a host to serve the file. Each one sees the piece it needs and no more.

Nothing is sold, rented, swapped or handed to an advertiser. The one other case would be a lawful request we are obliged to answer, such as a court order.

Cookies and analytics

This site sets no cookies and runs no analytics, no advertising pixels and no third-party trackers. Nothing follows you off the site.

Two honest footnotes. The fonts are loaded from Google Fonts, so your browser makes a request to Google's servers to fetch them. And our host keeps ordinary server access logs, as every web server does.

If analytics are ever added, they will be named here: .

Nothing about what you read

This book is read privately and we have no way of knowing anything about how you read it. There is nothing in the file that reports back — no tracking inside the PDF, no record of which part you opened, and nothing written down anywhere about your situation. What you write in a notebook stays in your notebook.

What you can ask for

You can ask for a copy of what we hold about you, ask us to correct it, or ask us to delete it. Write to Harshriddles@gmail.com from the address you bought with and we will answer within thirty days.

There is one limit, and it is the only one: a bare record of the sale — date, amount, reference — may have to stay in the accounts, because tax law says so. Everything else goes.

If you would rather start with a regulator, you can also complain to the data protection authority where you live.

Keeping it safe

Download links are short-lived and tied to the order. The small number of records we do hold sit behind accounts with strong passwords and two-factor login, and only the people running the shop can reach them. No system is perfect; we keep the pile small so that there is little to lose.

Children

This book is for adults and the shop is not aimed at anyone under 18. We do not knowingly collect anything from a child. If you think we have, tell us and it will be deleted.

Changes, and where to write

If this changes, the date at the top changes with it. Questions go to Harshriddles@gmail.com. The law of India applies here, as it does to the terms.
