Terms and Conditions

Last updated: July 12, 2026Version 2026-07-17

These terms govern the use of the Walden Lab platform and the purchase of its courses. By creating an account or buying a course, you accept what is stated here. Please read them: they are a contract between you and us.

They are governed by Law 1480 of 2011 (Consumer Statute), Law 527 of 1999 (electronic commerce), and other applicable Colombian regulations.

Note on language. This is a courtesy translation. Walden Lab operates under Colombian law, and the Spanish version of these terms is the binding one. In the event of any discrepancy between the two, the Spanish text prevails.

1. Who we are

  • Provider: Julián Cifuentes, natural person acting as a merchant.
  • Tax ID (NIT): 1.032.446.532-9
  • Trade name: Walden Lab
  • Domicile: Bogotá, Colombia
  • Address for judicial notices: Calle 81 #113-46, Bogotá, Colombia
  • Email: julian.cifuentes@thewaldenlab.com
  • Phone: +57 3112149132

2. What Walden Lab is

Walden Lab is an online training platform aimed primarily at psychology professionals who want to learn programming, data analysis, and artificial intelligence applied to their field.

Nature of the service: informal education. Our courses constitute informal education within the meaning of article 2.6.6.8 of Decree 1075 of 2015 and article 47 of Decree Law 2150 of 1995. They last fewer than one hundred and sixty (160) hours. This means — and it is important that you are clear on it before buying:

  • They do not lead to a degree or academic qualification.
  • They do not lead to a certificate of occupational aptitude.
  • We do issue a certificate of attendance to those who meet the requirements stated on the course page. It evidences attendance and the work done, not a professional licence.

3. What you are buying

The particular characteristics of each course — start date, number of weeks and sessions, hours, format, places available, syllabus, prerequisites, requirements for obtaining the certificate, and how long access to the material lasts — are stated on the public course page, before you buy.

That page forms part of this contract and prevails over these general terms in everything relating to the specific characteristics of the course. What the page promises, we owe.

Unless the course page says otherwise:

  • Courses run by cohort, with a published start date and live classes over Zoom, which are recorded and published on the platform.
  • Access to the material lasts twelve (12) months from the start of the course.
  • We may substitute the instructor with another of equivalent qualifications if the one originally announced cannot teach the session. If the change substantially alters what was offered, section 9 applies.

4. Your account

To access the courses you need an account. When you create it:

  • You undertake to provide truthful information and to keep it up to date.
  • You declare that you are over 18 years of age.
  • The account is personal and non-transferable. Sharing your credentials so that another person can access content you purchased is grounds for suspension.

How far your responsibility goes. You are responsible for the use of your account when you make that use yourself, or when it results from your having shared your credentials or having failed to take reasonable measures to protect them. You are not responsible for unauthorized access originating in security failures attributable to Walden Lab or its providers.

Tell us immediately at julian.cifuentes@thewaldenlab.com if you believe someone accessed your account without your authorization.

5. Prices, purchase process, and payments

  • Prices are expressed in Colombian pesos (COP) and include applicable taxes. The price you see is the price you pay.
  • Before confirming, you will see a summary of the purchase: the courses, the price of each, any discounts applied, and the total. You can correct or cancel it up until the moment you confirm.
  • The purchase is completed by your express acceptance and payment.
  • Payments are processed through Wompi (Bancolombia). Your card details are entered directly into the gateway: Walden Lab neither receives nor stores them.
  • Your enrollment is activated when the gateway confirms payment, not when you start the purchase. If payment is left pending or is declined, the enrollment is not created.
  • We will send you the receipt for the transaction by email, no later than the following calendar day. It is also available at /dashboard/pedidos.

Pricing errors. If we detect an obvious pricing error before you confirm the purchase, we will correct it and you will see the correct price before paying. If the error is detected after the purchase is completed, we honour the price we quoted you, unless there is a demonstrable legal or technical impossibility, in which case we refund you 100%. Under no circumstances will we charge you a difference without your express authorization.

6. Points and discounts

The platform may award you points for your participation and progress, redeemable as a discount on future purchases. Regarding them:

  • They are not money. They are not redeemable for cash, are not transferable to another person, and do not earn interest.
  • Value: one (1) point equals a one per cent (1%) discount.
  • Cap: the accumulated discount may not exceed 20% of the cart value. The remainder is paid with the payment method you choose.
  • Future courses only: the discount applies to later purchases, not to the course on which you earned the points.
  • Validity: points expire twelve (12) months after being awarded. Your balance and its expiry date are always visible in your dashboard.
  • If you close your account, the points are lost.
  • If a purchase in which you used points is voided or refunded, the points are returned to your balance.
  • We may change the earning rules going forward, notifying you in advance. Points you have already accumulated are honoured.
  • We may cancel points obtained through fraud or a demonstrable technical error. If that happens, we will tell you the reason, and you can dispute it through the channel in section 15.

7. Right of withdrawal and refund policy

There are two different things here, and it is worth not confusing them: one is given to you by law, the other we give you because we want to.

7.1. The legal right of withdrawal (retracto)

Where article 47 of Law 1480 of 2011 applies, you may exercise the right of withdrawal within the five (5) business days following the conclusion of the contract. We must return your money without deductions within the thirty (30) calendar days that follow.

Note that the law provides that withdrawal may not apply where provision of the service has already begun with your agreement before that period expired.

7.2. Our voluntary satisfaction policy

Regardless of whether the legal right of withdrawal applies, Walden Lab voluntarily grants you the following:

You may request a full refund of a course at any time from purchase until five (5) business days after the course's published start date.

That is: you can start the course, attend the first sessions, and, if it is not for you, ask for your money back within that period. It is more than the law requires of us, and we do it so that you can buy with peace of mind.

How to request it. Write to us at julian.cifuentes@thewaldenlab.com from your account's email address, indicating the course and the reason (the reason helps us improve; it is not a requirement for granting it).

How we return the money. Preferably by the same payment method you used, within the thirty (30) calendar days following your request. If for technical reasons of the gateway or the issuer that is not possible, we will agree another method with you that does not cause you additional costs. Once the refund is accepted, your access to the course is deactivated.

7.3. What does NOT end when those periods expire

The expiry of the legal withdrawal period or of our voluntary policy does not leave you without rights. The legal warranty remains alive: if the service does not meet what was offered, has quality or fitness defects, is not made available, or there is any other breach attributable to us, you may demand the remedies of the Consumer Statute — correction of the fault, re-performance of the service, rescheduling, or a refund, as appropriate. This has no five-day limit: it is governed by law.

8. Payment reversal

Under article 51 of Law 1480 of 2011, where the purchase was made using electronic payment means, you may request a reversal of the payment in the cases provided by law, including:

  • fraud;
  • an unsolicited transaction;
  • the service was not provided;
  • the service does not correspond to what you requested or to the characteristics stated;
  • the service was defective or non-conforming.

The request must be made within the five (5) business days following your becoming aware of the fact, to us and to the issuer of the payment instrument.

9. Changes, cancellation, and availability

Rescheduling a live session. If we have to move a session, we will notify you as far in advance as possible and offer you a reasonable new date.

We do not replace a live class with a recording without telling you. We sell live training, and that is an essential characteristic of what you bought. We will only do so if it was stated in advance on the course page or if you accept it. If the change substantially alters what was offered, you may request an equivalent alternative or termination of the contract with the corresponding refund.

If we cancel a course before it starts, we refund 100% of what you paid, regardless of the periods in section 7.

If we cancel a course already under way, we refund at least the proportional part not delivered. And if the cancellation causes the course to lose its purpose for you, you may request a full refund: we are not going to leave you with half a course that is of no use to you.

If we fail to make the service available within the promised time, you may demand its immediate provision or terminate the contract and obtain the refund the law provides.

Platform availability. There may be interruptions due to maintenance or to failures of our providers. We will do what is reasonable to minimize them, but we do not guarantee uninterrupted availability.

Force majeure. Neither party is liable for breaches caused directly by unforeseeable and irresistible events outside its reasonable control. The affected party must give timely notice, take measures to reduce the impact, and resume performance as soon as possible. If the situation prevents delivery of an essential part of the course for a period that makes it lose its purpose, you may request a reasonable alternative or the corresponding termination. Force majeure does not cover ordinary maintenance failures, lack of staff, or foreseeable problems.

10. Intellectual property

Our content

All course material — videos, recordings, code notebooks, slides, texts, and exercises — is the property of Walden Lab or of its instructors.

Your licence. When you buy a course you receive a personal, non-transferable licence to access that material for individual learning purposes, for the access period stated on the course page (by default, twelve months from the start).

When we can revoke it. Only for proven breach of these terms, fraud, infringement of third-party rights, or security risks, and always respecting your rights as a consumer. We do not revoke it at our discretion: if you paid, the access is yours for the period stated.

What you may download. You may download and keep the materials we expressly enable for that purpose: code notebooks, data files, templates, and working material. They are tools — they exist for you to use them, modify them, and keep using them after the course.

What you may not do. Copy, record, resell, redistribute, publish, or share the course content outside the platform, or use it to deliver your own training, without our written authorization. This includes sharing your credentials and redistributing the recordings of live classes.

Your content

The code, analyses, and work you produce during the course are yours. You retain ownership of them.

You grant us a non-exclusive, royalty-free, and limited licence to reproduce and display that work within the course, and only for as long as is necessary for its assessment, feedback, and academic participation (for example, in forums or in peer review). When work of yours is going to be shown to other students, the platform will tell you beforehand.

If we wanted to use your work for promotional purposes, we would ask for express and separate permission. Accepting these terms does not give us that permission.

Your image and voice in the recordings

Live classes are recorded, and the recordings are published on the platform for the students on the course.

  • If you take part with your camera or microphone on, your image, your voice, and your contributions will be in the recording.
  • You may always take part with your camera off. You can also ask questions in the chat.
  • The recording is visible only to those enrolled in that course, during the access period.
  • You may not redistribute it outside the platform.
  • To use an excerpt for promotional purposes we will ask for express and separate authorization. Acceptance of these terms is not enough for that.

11. Use of the artificial intelligence assistants

The platform includes assistants based on AI models. By using them, you understand that:

  • Their answers may contain errors and may be incomplete, out of date, or reflect biases. They are an aid to learning, not a source of truth: they do not replace consulting the original sources or your own professional judgement.
  • They do not constitute clinical, psychological, legal, or professional advice of any kind.
  • The text you write to them is sent to an external provider (Anthropic, in the United States) to generate the response. We do not send your name or your email address.
  • The assistant evaluates your preparation answers, and that evaluation affects the points you earn (section 6), which translate into discounts. It does not affect your grade, your certificate, or your standing in the course. Your instructor can review and correct that evaluation, and you can request human review by writing to julian.cifuentes@thewaldenlab.com.
  • You must not enter identifiable information about patients or clients, or confidential third-party data. This obligation is especially serious for those practising psychology (Law 1090 of 2006).

The detail of what is sent, what is retained, and for how long is in the Personal Data Processing Policy, section 8.

12. Community conduct

The forums and discussion spaces exist so that we can learn together. The following is prohibited:

  • Harassing, discriminating against, or attacking other students or instructors.
  • Posting identifiable information about patients or third parties.
  • Sharing or requesting pirated material, or course content outside the platform.
  • Spamming or unauthorized commercial promotion.

What happens if you breach this

Serious breaches. The following, and only the following, are considered serious breaches:

  1. The distribution or sale of course content outside the platform.
  2. Fraudulent access or the use of someone else's credentials.
  3. Serious harassment, threats, or aggression towards another student or an instructor.
  4. The deliberate publication of identifiable patient data or third-party data.
  5. Attempts to compromise the security of the platform.
  6. Repeat offending after a formal warning.

Procedure. Unless there is an immediate risk to other people or to the security of the platform, we will inform you of the breach and you will be able to explain yourself before the cancellation becomes final. We do not cancel accounts by surprise.

Financial consequences. They will be proportionate to the seriousness of the breach, to the part of the service already delivered, and to the losses we can demonstrate. We do not automatically retain 100% of what was paid, and in no case are the non-waivable rights the law grants you as a consumer affected.

13. Liability

We undertake to deliver the educational service with diligence and quality, and we answer for it in accordance with the Consumer Statute.

We do not guarantee employment, financial, or professional outcomes from taking a course: they depend on your dedication and on many factors outside the training. Nor are we liable for failures of your equipment or your connection, or for the professional decisions you make on the basis of what you have learned.

That exclusion does not limit the liability that legally falls to us for the quality, fitness, safety, information supplied, and performance of the service offered, or for our own negligence. Nothing in these terms limits the non-waivable rights that Colombian law grants you as a consumer.

14. Personal data

The processing of your personal data is governed by our Personal Data Processing Policy, which forms an integral part of these terms.

15. Consumer support (PQR)

Any petition, complaint, or claim may be submitted:

On receiving it we will assign a case number and send you a confirmation with the date and time. With that case number you can follow up through the same channel.

We will respond within the fifteen (15) business days following receipt, with the reasons and evidence on which our response is based.

If you are not satisfied, you may turn to the Superintendence of Industry and Commerce: www.sic.gov.co.

16. Governing law and jurisdiction

These terms are governed by the laws of the Republic of Colombia.

Disputes will be heard by the competent administrative or judicial authority under Colombian law, respecting the venues and protection mechanisms granted to consumers, including your access to the Superintendence of Industry and Commerce. Nothing here obliges you to sue in Walden Lab's place of domicile.

17. Changes to these terms

We may update these terms. Substantial changes will be communicated to you with reasonable advance notice and will not affect purchases you have already made, which are governed by the terms in force at the time of your purchase.

Mere continued use of the platform will not be used to retroactively impose new financial obligations or new restrictions on courses you have already bought.

The date of the last update appears at the top of this document.

18. Effective date

These terms are effective as of 12 July 2026.
