Memory techniques and mental skills, on the web

Learn the methods behind remembering, then practise them in a simple app.

Bidcrest Group develops and sells educational web apps that teach memory techniques and mental skills: the memory palace, systems for numbers, names and faces, mental arithmetic and learning by heart. Whichever of our five languages you prefer (English, French, Spanish, Italian or German), you can read this site and write to our support team in it.

About us

A small software and publishing company for mental skills

Bidcrest Group LLC was formed in Wyoming, United States, as a limited liability company. We write and program educational web apps on memory techniques and mental skills, offer them in five languages and sell them directly to consumers.

Plenty of everyday moments call on what you can keep in your head: a list you would rather not write down, a number someone reads out, the name of a person you have just met, a poem or a speech you want to know by heart, a sum at the till.

There are well-known methods for exactly these moments, and they can be learned. Our job is to explain them clearly, give you material to practise with and keep the software out of your way.

From start to finish, the work on an app stays with us. It begins with research, writing the lessons and programming the app. Once an app is live, we run the platform, deliver access online, answer billing questions and look after customers. The one step we hand over is taking the payment, which third-party payment processors do on our behalf.

  • Our apps are used online only, with no physical product and no shipping.
  • Some apps are a single payment, others a subscription.
  • Questions on access, billing or your account get an email answer from us in 48 business hours or less.

Educational content. Our products teach practical techniques and offer general information and tools. They are not medical, psychological, nutritional, legal or financial advice and do not promise any particular result. For advice about your own circumstances, consult a qualified professional.

How to buy

From picking an app to your first practice session

You see every condition before paying, you pay on a secure page, and the app is yours to use once the payment goes through.

Choose an app

Each app has a dedicated page describing its lessons, its practice tools, how it is used and the access you get.

Check the details

Before you pay, read at your own pace the description, the price in the currency you pick (US dollars or euros), the billing frequency, how renewal works, the access information and the policies that apply.

Pay on a secure page

The payment itself happens on an encrypted (HTTPS) page operated by our payment processor.

Begin practising

All our products are digital and nothing is sent by post. Access is online and opens as soon as your payment is confirmed.

Bookmark the app in your browser when it opens, so it is one click away next time.

Every app is a little different. Contents, features, languages and access terms vary from one to the next, and so can the price, the currency, how often you are billed and the renewal conditions. The product page and the checkout page show all of this before you complete payment.

Bidcrest Group sells only digital products, so there is never anything physical to ship.

What you will find in every app

Runs in the browser

There is no installation to deal with. A compatible phone, tablet or computer with an up-to-date browser does the job.

Your work is kept

The palaces you build, the lists you make and the sessions you complete are stored for you in your personal space. The Privacy Policy describes how this works.

Clear explanations

Each technique is explained in short lessons with worked examples and exercises you can do straight away. No jargon, no padding.

Printable sheets

Every app comes with material you can print, such as reference cards, blank palace plans or practice sheets.

Simple billing

Some apps are paid once for an access period shown before you pay. Others are subscriptions, and you can end them online whenever you like.

Help by email

Our support team replies within 48 business hours, Monday to Friday.

How we work

Three principles we keep to

One job per app

Each app teaches one group of techniques. If a feature would distract from that, we leave it out.

Conditions first

Price, billing, renewal, access and cancelling are spelled out in plain language on the page, before any payment.

Easy to reach

Every email gets an answer. Cancelling takes a single form, linked in the footer of each page.

Customer support

Ask us anything: answers within 48 business hours

Ask us about access, your account, billing or a subscription. We also handle cancellations, refunds, withdrawals, complaints and any other matter linked to a purchase.

Help with an order

Write to this address about getting into an app, your account, billing, subscriptions, cancelling, refunds, withdrawing or a complaint.

FAQ

Questions we hear a lot

Your question is not here? Send us an email and we will answer it.

All our products are digital and nothing is sent by post. Access is online and opens as soon as your payment is confirmed.

Bookmark the app in your browser when it opens, so it is one click away next time.

As a rule, no. Our apps are almost all web-based: they open in the browser without any separate program. The access details are specific to each app.

You can. The apps are designed for the browser on compatible phones and tablets as well as on computers.

It varies by app: a few are bought with one payment, others give access by subscription. In both cases the billing frequency and the renewal conditions are shown to you before the purchase is complete.

Go to “Cancel contracts here” whenever you wish, or write to us by email. The app remains available to you until the period you paid for has run out. The full rules sit in the Cancellation Policy.

Our 7-day refund policy: for 7 days after any charge, you may ask us to refund that charge in full, even if you have started using the product. This is a voluntary extra that sits alongside your statutory rights, including any statutory right of withdrawal, and never limits them.

Send your request to support@bidcrestgroup.com. How refunds work, step by step, is described in the Refund Policy.

If you are a consumer in the European Union or the European Economic Area, the law gives you 14 days from the conclusion of your contract to withdraw from it, without stating a reason. Those 14 days run from your first purchase; a renewal does not restart them. You can withdraw on our withdrawal page (“Withdraw from contract here”, linked in the footer of every page) or by emailing support@bidcrestgroup.com.

A digital service, and a subscription counts as one, remains open to withdrawal until the 14 days are over. If the service started straight away because you asked for it, you pay only a proportionate amount covering the time until you withdrew.

Digital content supplied in a single delivery follows another rule: the right of withdrawal ends when supply begins, but only if three conditions are all met. You expressly requested immediate supply, you acknowledged that you would lose the right, and we confirmed this to you on a durable medium.

Our Right of Withdrawal page explains which situation applies to you and from when.

Can't find your access, or the product won't load? Email support@bidcrestgroup.com. We will get your access working again or, if we cannot, cancel the order and refund it.

Email works best: support@bidcrestgroup.com. If the message concerns an order, quoting your checkout email address lets us find it.

Our support team replies within 48 business hours, Monday to Friday.

Payments are collected for us by one or more third-party payment processors, whose name appears on the secure payment page and on the receipt. The seller is Bidcrest Group LLC, which stays responsible for your order, its delivery, customer support and any refund.

You type your card details on an encrypted (HTTPS) payment page operated by our payment processor, a company certified under the Payment Card Industry Data Security Standard (PCI DSS). Our own systems never keep your full card number or security code, and we will never ask for card details by email.

Charges from us show on your bank or card statement with a descriptor that includes "BIDCREST". The rest of the wording can change with the product and the bank.

Seeing a charge you don't recognise? Send support@bidcrestgroup.com the date, the amount and the last four digits of the card used. Do not send the full card number or the security code.

Our support team replies within 48 business hours, Monday to Friday.

We offer our apps in English, French, Spanish, Italian and German, but not every app comes in every language. The page of each app says which languages it has and where it can be bought.

We are a limited liability company organized in Wyoming. Our principal office is in Doral, Florida (United States), and our customers abroad are served in five languages (English, French, Spanish, Italian, German).
