Terms of Service

1.Acceptance

By subscribing to any MarketStack product, whether free or paid, creating an account, signing in, or continuing to access the Service, you agree to these Terms. If you do not agree, do not subscribe, sign in, or continue to use the Service.

These Terms apply equally at every tier, including the free tier, and whether the Service is accessed via Substack or via marketstack.pro. A free subscription grants less access; it does not grant broader rights or exempt you from clauses 4, 5, 6, 7 or 8.

2.Licence granted

A personal, non-exclusive, non-transferable, revocable licence to access those parts of the Service your subscription tier permits, for your own personal or internal business research and investment decision-making. Nothing further is granted. The licence is identical in scope at every tier; a higher tier grants more access, not broader rights.

3.Definitions

“the Service”

means the MarketStack publication at marketstack.substack.com and its custom domain, the MarketStack Terminal at marketstack.pro and its subdomains, any MarketStack email newsletter, and any other property MarketStack operates under the MarketStack name, together with all content, data, and output made available through them.

“Competing Product”

means any product or service providing substantially similar functionality to the Service, including rating, ranking, grading, scoring, tracking, aggregating, or analysing the performance, positioning, or output of investment newsletters, financial publishers, or financial content creators.

“Confidential Information”

means the implementation detail of the Service that MarketStack has not published in full, including its methodology, data structure, classification and tier systems, scoring logic, sourcing approach, extraction and verification process, data schema, and product architecture, together with any feature or capability not publicly announced by MarketStack. Confidential Information includes the combination and configuration of those elements as a whole, whether or not individual elements have been described publicly.

4.Restrictions

4.1Principle

MarketStack measures publicly available and lawfully accessed output from financial publishers. It does not claim ownership of anyone’s underlying commentary or calls, and these Terms are not intended to prevent anyone from reading, quoting, discussing, or independently measuring publicly available material. What these Terms restrict is the reconstitution of MarketStack’s dataset and the reuse of its architecture to build a competing product.

4.2Restrictions

You may not, directly or indirectly, at any tier:

1. systematically extract, copy, download, scrape, spider, crawl, store, or reproduce substantial portions of the Service or its data, for the purpose of reconstituting all or part of the MarketStack dataset or developing a Competing Product;
2. use the Service, or anything observed within it, to design, develop, specify, train, benchmark, or improve any Competing Product;
3. reverse engineer or attempt to derive the structure, logic, scoring methodology, classification system, data schema, or sourcing method underlying the Service;
4. share login credentials or permit any other person to access the Service through your account or subscription;
5. use the Service for competitive analysis, market research, or due diligence on behalf of any third party developing or evaluating a Competing Product;
6. republish or redistribute substantial extracts of the Service’s data or output as a standing or systematic feed to any third party.

4.3What these restrictions do not prevent

Nothing in clause 4.2 prevents you from:

1. reading, saving, or printing material for your own use;
2. quoting or citing MarketStack with attribution, including in published work;
3. sharing an individual screenshot, chart, or figure, with attribution;
4. where you are a tracked author, reviewing, disputing, or correcting your own record;
5. independently obtaining, analysing, or measuring publicly available material from any publisher, including material MarketStack also measures.

5.Competitor access

5.1Obligation

You must not access or use the Service on behalf of, or for the benefit of, any Competing Product.

5.2Confirmation

You confirm, on subscribing and on each occasion you access the Service, that:

1. you do not access the Service on behalf of any person or entity that operates or is actively developing a Competing Product;
2. the registration information you provide is not materially false or misleading and is not intended to conceal an affiliation of that kind.

5.3Change of circumstances

If clause 5.1 ceases to be satisfied you must stop accessing the Service and notify hi@marketstack.pro. Your authorisation to access the Service is automatically revoked at that point.

5.4Scope

This clause is directed at use on behalf of a Competing Product. It does not restrict journalists, academics, analysts, or consultants accessing the Service for research, reporting, or advisory work that is not for the benefit of a Competing Product.

6.Permitted purpose of published material

MarketStack publishes material describing its methodology, architecture, sourcing model, classification structure, and features. This is disclosed to subscribers at every tier solely for the permitted purpose in clause 2 — to inform your own research and your assessment of the Service. It is not disclosed for you to use in building, specifying, or improving a Competing Product, and clause 4.2(b) applies to it in full regardless of which tier you received it through.

7.Confidential Information

7.1Confidential Information as defined in clause 3 is disclosed to subscribers solely for the permitted purpose in clause 2. You agree to keep it confidential and not to use or disclose it except as permitted by these Terms. This obligation survives termination and continues for three years.

7.2Exclusions

Confidential Information does not include information that:

1. was, as a body and in the precise configuration and assembly of its components, already generally known or readily accessible to persons within the circles that normally deal with that kind of information at the time of disclosure. The fact that individual elements have been described publicly does not of itself bring the combination within this exclusion;
2. becomes generally known, on the same basis, other than through a breach of these Terms by you;
3. you can show was already known to you, free of any confidentiality obligation, before disclosure;
4. you can show was independently developed by you without use of or reference to the Confidential Information;
5. you lawfully received from a third party free of any confidentiality obligation;
6. you are required to disclose by law, regulation, or court order, provided you notify MarketStack in advance where lawfully able to do so.

8.Database rights

The MarketStack dataset is a database in which MarketStack owns database right under the Copyright and Rights in Databases Regulations 1997. You may not extract or re-utilise all or a substantial part of its contents, nor repeatedly extract insubstantial parts in a way conflicting with normal exploitation of the database.

9.Intellectual property

All content, data, methodology, structure, and design of the Service are owned by MarketStack. No rights are transferred by subscription at any tier.

10.Privacy and logging

MarketStack logs account activity including sign-in times, session duration, and pages accessed, as described in its Privacy Policy.

11.Subscriptions, payment and cancellation

11.1Price and payment

Prices are as displayed at the point of subscription. Paid subscriptions are billed in advance and renew automatically at the end of each billing period unless cancelled. Payment is processed by Substack and Stripe; MarketStack does not store card details.

11.2Renewal and cancellation

You may cancel at any time through your subscription settings. Cancellation takes effect at the end of the current billing period, and you retain access until then. Price changes apply only prospectively and will be notified in advance.

11.3Statutory cancellation right (consumers)

If you are a consumer in the UK or EU, you have 14 days from the date of your subscription to cancel and receive a full refund, under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. MarketStack does not ask you to waive this right.

To cancel within the 14-day period, email hi@marketstack.pro or use your subscription settings. Refunds are issued to the original payment method within 14 days of cancellation.

This right applies to your initial subscription. Renewals of an existing subscription are not new distance contracts and do not restart the 14-day period.

11.4Nothing in this clause affects your other statutory rights, including under the Consumer Rights Act 2015 where digital content is not of satisfactory quality, fit for purpose, or as described.

12.Suspension and termination

MarketStack may suspend or terminate access where it reasonably believes these Terms have been breached, fraud has occurred, or continued access would materially harm the Service. Where access is terminated for a material breach by you, MarketStack is not obliged to provide a refund except where required by law. Where MarketStack ends the Service for reasons unrelated to your breach, it will provide a pro-rata refund for any unused prepaid period.

Clauses 4, 6, 7, 8, 9, 13, 14, 15, 16 and 17 survive termination.

13.Remedies

You acknowledge that a breach of clauses 4.2, 6 or 7 may cause harm that cannot be adequately compensated by damages alone. MarketStack may seek injunctive or other equitable relief, in addition to any other remedies available at law.

14.Assignment

MarketStack may assign these Terms as part of a sale or transfer of the business. You may not assign your rights without MarketStack’s consent.

15.Entire agreement and severability

These Terms constitute the entire agreement relating to the Service. If any provision is found unenforceable, the remaining provisions continue in full effect.

16.Governing law and disputes

These Terms are governed by the law of England and Wales.

16.1Business subscribers

If you subscribe on behalf of a business, or as part of your trade, profession or business, any dispute arising out of or in connection with these Terms shall be referred to and finally resolved by arbitration under the LCIA Rules, which are deemed incorporated by reference. The seat shall be London, England; the language English; the tribunal one arbitrator.

16.2Consumer subscribers

If you subscribe as a consumer, disputes shall be subject to the non-exclusive jurisdiction of the courts of England and Wales. Nothing in these Terms affects your rights under the Consumer Rights Act 2015 or other applicable consumer protection law, including any right to bring proceedings in the courts of your country of residence.

16.3Injunctive relief

Nothing in this clause prevents MarketStack from seeking urgent injunctive or other equitable relief in any court of competent jurisdiction, including any court in the jurisdiction where you are located.

16.4Other proceedings

Where clause 16.1 does not apply, MarketStack may bring proceedings in any other court of competent jurisdiction.

17.Changes to these Terms

MarketStack may update these Terms. Material changes will be notified to subscribers. Continued use after notification constitutes acceptance. If you do not accept a material change, you may stop using the Service and, where required by law, receive any applicable refund for the unused prepaid period. Every superseded version is retained and available on request.
