Terms of Service

Last updated: 24 April 2026

Thanks for using Pharos. When we say "Pharos," "we," "our," or "us," we mean Leadlynk Limited, a company registered in England and Wales (company number 15137196) with its registered office at 128 City Road, London, EC1V 2NX, United Kingdom. When we say "you," we mean the person or organization using Pharos. This is the contract between us. By creating a Pharos account or using the service, you agree to these terms.

If you're agreeing on behalf of a company, you're confirming you have authority to bind that company to these terms, and "you" in this agreement means both you personally and that company.

1. The account

You need a Pharos account to use the service. Keep your login credentials secure — you are solely responsible for all activity under your account, including activity by anyone you allow to access it. Let us know immediately at support@heypharos.com if you think someone else is using your account; until we receive such notice and have had a reasonable opportunity to act, any activity on the account is deemed authorized by you.

You must be at least 16 years old and able to form a binding contract where you live. You may not create an account if you were previously suspended or banned from Pharos.

2. What Pharos does

Pharos monitors how AI platforms (ChatGPT, Claude, Gemini, Perplexity, and others we may add or remove) talk about the brands, topics, and prompts you track. We send prompts to those platforms on your behalf, analyze the responses, and show you rankings, citations, sentiment, and competitor comparisons.

We will use reasonable efforts to keep Pharos running well, but we don't promise that any specific AI platform will always be available, that its responses will be consistent or accurate, or that Pharos will always support any particular platform. Which platforms are available, and what they return, is ultimately in their hands, not ours.

3. Acceptable use

You agree not to use Pharos to:

Monitor or target individuals (as opposed to brands, companies, or topics).
Submit illegal content, or content that infringes someone else's rights.
Overload our systems, probe or scan for vulnerabilities, or interfere with other customers or sub-processors.
Resell Pharos access, white-label the service, or scrape the product to build or train a competing service.
Violate the terms of the AI platforms we query on your behalf.

See our Acceptable Use Policy for the full list. We may update the Acceptable Use Policy from time to time; the current version applies to your use of Pharos.

4. Billing

Subscriptions. Pharos is billed in advance on a recurring basis — monthly or annually, depending on the plan you choose. Your payment method is charged automatically at the start of each period until you cancel. By subscribing, you authorize us (and our payment processor) to charge that payment method for each billing period and for any applicable taxes and overage fees.

Free trials. We may, at our sole discretion, offer free trials of Pharos or specific plans. If you start a trial:

The trial length, included features, and any conversion terms will be disclosed at signup.
Unless the signup flow clearly states otherwise and asks for your payment method, trials will not automatically convert to paid subscriptions; you will need to choose a plan to continue after the trial ends.
Where a trial does require a payment method and is set to auto-convert, we will clearly display the conversion date, plan, and amount before you begin, and send a reminder email before the first charge.
Trial access is a courtesy, not a binding offer. We may modify, limit, or withdraw a trial, or deny a trial to any user, at our sole discretion and without notice or liability.
Trial accounts may be subject to reduced quotas, fewer features, or shorter data retention than paid accounts.

Usage limits and quotas. Each plan includes specific limits — such as the number of prompts, brands, competitors, analyses, or API requests permitted per billing period. If you reach a limit, we may pause, throttle, or queue further usage, or treat the excess as overage chargeable at our then-current overage rates, in each case at our sole discretion. Unused quota does not roll over into a later period and is not refundable in cash or credit. We provide visibility into your quota in the dashboard, but we do not guarantee advance alerts and we are not liable for any consequences of you reaching or exceeding a limit. We may change plan quotas for new or future billing periods on the notice set out in "Price changes" below.

Cancellation. You can cancel anytime from your account settings. You'll keep access until the end of the current paid period. Except as set out in the "Consumer cancellation rights" paragraph below, we do not issue refunds for unused time on a monthly plan or for a partial month of service. For annual plans, we offer a pro-rated refund if you cancel within the first 30 days. After that, the annual subscription runs to the end of the current term.

Consumer cancellation rights (UK / EU). If you are an individual consumer (not a business) resident in the UK or EU, you have a statutory right to cancel within 14 days of subscribing, for any reason, and receive a refund. By starting to use Pharos during this period, you expressly request that the service begin immediately and you acknowledge that your right to cancel will end once the service has been fully performed within the 14 days. If you cancel during the period and have used the service, we may deduct a proportionate amount for what you have used.

Price changes. We may change pricing with at least 30 days' notice by email to the address on your account. Price changes will not affect your current billing period — they apply starting with your next renewal. If you don't accept a price change, your sole remedy is to cancel before the new price takes effect.

Failed payments. If a payment fails, we'll try again and email you. If we still can't collect within a reasonable period, we may suspend, restrict, or close your account and delete your data in accordance with the Privacy Policy. Unpaid fees continue to accrue and remain payable.

Taxes. Prices are shown in USD and don't include VAT, GST, sales tax, withholding, or similar. Where we are required to charge tax, we will add it at checkout. Where you are required to withhold tax, you must pay us the amount needed so we receive the full price after the withholding.

Currency and FX. All Pharos pricing is in US Dollars. If your card or bank account is denominated in another currency, your issuer will convert the charge and may add a foreign-exchange or cross-border fee. Those fees are set by your issuer and are not refundable by us.

5. Your content

You keep all rights to the brand names, prompts, competitor data, and other content you submit to Pharos ("Your Content"). You grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit, process, analyze, and display Your Content solely to provide and improve the service for you and, in aggregated and anonymized form (from which you cannot reasonably be identified), to operate and improve Pharos generally.

We don't claim ownership of Your Content and we don't use it to train third-party AI models.

Your warranties about Your Content. You represent and warrant that: (a) you have the legal right to submit, host, and process Your Content through Pharos; (b) Your Content does not infringe any copyright, trademark, trade secret, privacy, publicity, or other right of any third party; (c) you have a legitimate reason to monitor any brand, organization, or term you submit, and you are not using Pharos to harass, defame, or unlawfully profile any person; and (d) if you submit content on behalf of an organization, you are authorized to do so.

6. Our intellectual property

Pharos, including its software, user interface, models, prompts, scoring methodology, aggregated and anonymized insights, documentation, logos, trade marks, and all related materials, is owned by Leadlynk Limited (or our licensors) and protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, non-sublicensable right to access and use Pharos during your subscription, solely for your internal business purposes and subject to these terms. No other rights are granted.

You may not: (a) copy, modify, distribute, publicly display, or create derivative works of Pharos; (b) reverse-engineer, decompile, or attempt to extract the source code, models, or prompt structures of Pharos, except to the extent applicable law expressly permits despite this restriction; (c) remove or alter any proprietary notices; or (d) use Pharos to benchmark or train a competing product.

7. Feedback

If you send us suggestions, ideas, bug reports, or other feedback about Pharos, you grant us a perpetual, worldwide, irrevocable, royalty-free licence to use, modify, and incorporate that feedback without obligation or compensation to you. Feedback is not considered your confidential information.

8. Changes to the service

We are constantly improving Pharos. We may add, modify, replace, remove, or discontinue features, integrations, models, or sub-processors at any time. For material reductions to features included in a paid plan, we will give reasonable notice (typically at least 30 days by email) so you can decide whether to continue. Whether a change is a "material reduction" is determined by us acting reasonably. Non-material changes — including new features, UI updates, bug fixes, security changes, and changes to how we deliver a feature — may take effect immediately.

9. AI data flow

To provide the service, Pharos sends prompts and brand information to third-party AI platforms and stores their responses in your account. Those platforms are listed in our Sub-processors page and described in our Privacy Policy. By using Pharos you acknowledge that this data flow is necessary to deliver the service and you authorize it. You further acknowledge that the third-party platforms are independently operated, that their availability and output are outside our control, and that we are not responsible for how they process or respond to any prompt.

10. Availability and support

We aim for high availability but do not promise any specific uptime, response time, or continuity of service unless we have signed a separate SLA with you. If you have a problem, email support@heypharos.com and we'll respond during business hours. Support is provided on commercially reasonable best-efforts basis; we do not guarantee a resolution.

Scheduled maintenance and updates. We may take Pharos offline or degrade specific features for maintenance, upgrades, security patches, or to respond to issues at our sub-processors, at any time and where possible with prior notice.

Beta and preview features. We may from time to time offer features labelled "beta," "preview," "experimental," or similar. Those features are provided as-is, with no SLA, and may be changed, limited, or withdrawn at any time without notice. Beta features are not considered part of the paid service, and to the maximum extent permitted by law no liability cap, indemnity, warranty, or service commitment applies to them beyond what English law requires as a minimum.

11. Warranties and liability

Pharos is provided "as is" and "as available." To the maximum extent permitted by law, we disclaim all warranties, whether express, implied, or statutory, including warranties of merchantability, satisfactory quality, fitness for a particular purpose, non-infringement, accuracy, reliability, completeness, timeliness, or that Pharos will be uninterrupted, error-free, or secure. We do not warrant that rankings, sentiment scores, citations, competitor data, traits, or any other output will be correct, complete, current, or free from bias or error.

AI outputs are probabilistic. Pharos depends on third-party AI platforms (OpenAI, Anthropic, Google, Perplexity, and others) to generate the raw material we analyze. Those platforms can and do produce incorrect, biased, outdated, or hallucinated content. Pharos's analyses of that content inherit those limitations. You are responsible for independently verifying any Pharos output before acting on it, and you agree we are not liable for business, commercial, reputational, legal, financial, or other decisions you make in reliance on Pharos outputs.

Not professional advice. Pharos does not provide legal, financial, investment, tax, marketing-strategy, compliance, or other professional advice. Any output is informational only and does not constitute advice on which you should rely.

Liability cap. To the maximum extent permitted by law, our total aggregate liability to you for any and all claims arising out of or relating to these terms or your use of Pharos — whether in contract, tort (including negligence), statute, or any other theory — is limited to the lesser of (a) the total amount you actually paid us for the service in the 12 months immediately before the event giving rise to the claim, or (b) one hundred US dollars (USD 100) if you have not paid us anything in that period. We are not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, lost goodwill, or business interruption — even if we were advised such damages were possible, and even if a limited remedy fails of its essential purpose.

Essential purpose. The limitations and exclusions in this section apply to the fullest extent permitted by law, and survive termination, even if a limited remedy is found to fail of its essential purpose.

What we don't exclude. Nothing in these terms limits liability that cannot be limited by law — such as liability for fraud, fraudulent misrepresentation, death or personal injury caused by our negligence, or any other liability that cannot lawfully be excluded or restricted under English law.

12. Your indemnity to us

You agree to defend, indemnify, and hold harmless Leadlynk Limited and its officers, directors, employees, contractors, and agents from and against any third-party claim, demand, loss, damage, liability, cost, or expense (including reasonable legal fees) arising out of or relating to:

(a) Your breach of these terms, the Acceptable Use Policy, the Privacy Policy, or any applicable law.
(b) Your Content, including any claim that it infringes someone's rights or misrepresents a brand, organization, or person that you do not have a legitimate basis to monitor.
(c) Your violation of the terms of a third-party service (including the AI platforms Pharos queries on your behalf) or of any integration you connect to Pharos.
(d) Your negligence or wilful misconduct.
(e) Misuse of Pharos by anyone you allow access to your account, including employees, contractors, or agents.

We will tell you promptly about any claim we are seeking indemnity for, and you get reasonable control of the defence — but you may not settle any claim in a way that imposes any obligation on us (financial or otherwise), or that admits any fault or wrongdoing by us, without our prior written consent.

13. Force majeure

Neither party is liable for failure or delay caused by events beyond reasonable control — including outages at our hosting, payment, or AI-platform providers, internet or telecommunications failures, natural disasters, pandemics, strikes, cyberattacks, war, terrorism, or government action. The affected party must give prompt notice and use reasonable efforts to resume performance. This clause does not excuse your obligation to pay any amount owed.

14. Export controls and sanctions

You represent and warrant that: (i) you are not located in, under the control of, or a national or resident of any country or region subject to comprehensive economic sanctions by the United Kingdom, European Union, or United States; (ii) you are not on any restricted-party, denied-parties, or sanctioned-parties list maintained by those authorities; and (iii) you will not use Pharos in violation of any applicable export-control or sanctions law. We may suspend or terminate service immediately, without refund, if we reasonably believe these representations are or have become untrue, or if providing the service would expose us to sanctions or regulatory risk.

15. Your compliance responsibility

You are solely responsible for ensuring that your use of Pharos complies with all laws and regulations applicable to you, your organization, and the activities you undertake through the service — including data protection, consumer protection, advertising, competition, intellectual property, and sector-specific rules. We do not monitor your use for compliance, and we do not provide legal, compliance, or regulatory advice. Determining whether Pharos is suitable for a given use case in your jurisdiction is your responsibility.

16. Time limit on claims

Except where the law of your country as an individual consumer requires otherwise, any claim or cause of action arising out of or relating to these terms or your use of Pharos must be brought within 12 months of the date the claim first arose. After that period, the claim is permanently waived and barred. This clause does not apply to claims that cannot lawfully be time-limited.

17. Termination

You can cancel anytime from your account settings.

We may suspend, restrict, or terminate your account, or your access to any feature, at any time if: (a) you materially breach these terms, the Acceptable Use Policy, or any law; (b) we reasonably suspect fraud, abuse, or activity that endangers the service or other customers; (c) your account is inactive for an extended period and we give you notice; (d) a sub-processor withdraws a capability we rely on; or (e) we are required to by law, regulation, or binding order. We will give notice where we reasonably can. Suspension or termination does not entitle you to a refund except where expressly required by law.

When your account ends, Your Content is retained for 30 days during which you can export it, and then permanently deleted, subject to our retention obligations in the Privacy Policy. We may retain de-identified and aggregated data derived from Your Content that cannot reasonably be traced back to you.

18. Changes to these terms

We may update these terms from time to time. If we believe a change is material — for example, changes to pricing structure, billing, liability limits, indemnity, or acceptable use — we will give at least 30 days' notice by email to the address on your account and by updating the "Last updated" date at the top of this page. Non-material changes — such as typographical corrections, clarifying wording, updates to contact information, or additions of new sub-processors — may take effect immediately upon being published. Whether a change is material is determined by us acting reasonably.

Continuing to use Pharos after changes take effect means you accept the updated terms. If you do not accept a change, your sole remedy is to cancel your account before the effective date; your cancellation rights under §4 continue to apply.

19. Copyright and DMCA

We respect intellectual property rights. If you believe content in Pharos infringes your copyright, send a notice to copyright@heypharos.com including:

Identification of the copyrighted work claimed to be infringed.
Identification of the material claimed to be infringing, with enough detail for us to locate it (URL or account reference).
Your contact information (name, address, email, phone).
A statement that you have a good-faith belief that the use is not authorized by the rights holder, its agent, or the law.
A statement, under penalty of perjury, that the information in the notice is accurate and that you are the rights holder or authorized to act on their behalf.
Your physical or electronic signature.

We review valid notices and may remove or disable the allegedly infringing material. We may terminate accounts of repeat infringers. Knowingly submitting a false or bad-faith notice may expose you to liability.

20. Governing law and disputes

These terms, and any non-contractual obligations arising out of or in connection with them, are governed by the laws of England and Wales. Any dispute that cannot be resolved informally will be decided by the courts of England and Wales, which will have exclusive jurisdiction — except that either party may seek injunctive or other equitable relief in any court with jurisdiction to protect intellectual property, trade secrets, or confidential information.

If you are an individual consumer in the EU/UK, nothing in this clause overrides your statutory right to bring proceedings in your country of residence, or to rely on mandatory provisions of the law of that country.

21. Everything else

Assignment: you may not transfer these terms without our prior written consent, and any attempt to do so is void. We may assign or transfer these terms, in whole or in part, in connection with a merger, acquisition, reorganization, or sale of substantially all our assets.
No waiver: our failure to enforce any right or provision of these terms is not a waiver of that right. A waiver is only effective if given in writing and signed by us.
Severability: if any part of these terms is found unenforceable, it is modified to the minimum extent needed to make it enforceable, and the rest of the terms remains in full effect.
Entire agreement: these terms, plus our Privacy Policy, Cookie Policy, Acceptable Use Policy, and (if applicable) DPA, are the whole agreement between us, and supersede any prior or contemporaneous oral or written statements.
No third-party beneficiaries: these terms are between you and Leadlynk Limited. No other person has any right to enforce any part of them, whether under the Contracts (Rights of Third Parties) Act 1999 or otherwise.
No agency or partnership: nothing in these terms creates any agency, partnership, joint venture, employment, or fiduciary relationship between you and us. Neither party can bind the other.
Notices: notices to us must be sent to support@heypharos.com (or, for legal notices, to our registered office). Notices to you will be sent to the email address on your account and are deemed received when sent. You are responsible for keeping that address current and monitored.
Electronic communications: you agree to receive all notices, disclosures, and communications from us electronically. Electronic communications satisfy any legal requirement for a written communication.
Headings: section headings are for convenience only and do not affect interpretation.
Survival: the following sections survive termination or expiry of these terms: §3 (Acceptable use), §4 (Billing — for unpaid amounts and for refund limits), §5 (Your content — warranties and licence), §6 (Our intellectual property), §7 (Feedback), §11 (Warranties and liability), §12 (Your indemnity), §14 (Export controls), §15 (Your compliance responsibility), §16 (Time limit on claims), §17 (Termination — data handling after termination), §19 (Copyright), §20 (Governing law and disputes), and this §21.
