Terms of Use

Last updated: 2026-05-24. These terms govern your use of letguru.app.

1. Parties

This agreement is between you (the "user") and ALANDALA SOFTWARE SOLUTIONS SRL, a Romanian limited-liability company ("we", "us", "letguru"). Full operator details (tax ID, trade-register number, registered seat) are at letguru.app/imprint.

2. Scope of these terms

By creating an account, signing into letguru.app, or otherwise using the service, you agree to these Terms of Use and to our Privacy Notice. If you do not agree, do not create an account and do not use the service.

3. Service description

Letguru is an information-only tennis-statistics service. We publish structured statistical data and pattern frequencies about professional tennis matches (across the ATP, WTA, and Challenger tours and Grand Slams, men's and women's singles). These insights are derived from public match data and statistical analysis; letguru does not predict match outcomes, and no outcome is guaranteed.

Letguru does not offer gambling, betting, sports-investment, or financial advice. Any use of letguru insights in connection with a wager or financial decision is the user's sole responsibility, and users must comply with the gambling and consumer-protection laws of their own jurisdiction.

4. Account terms

  • Age requirement: you must be at least 18 years old to create an account. Romanian Civil Code Art. 41–42 limits the contractual capacity of minors; underage accounts will be suspended on discovery.
  • One account per person: duplicate accounts may be merged or suspended at our discretion.
  • Truthful information: the email address and any other identifying information you provide must be accurate. You may delete your account at any time via the in-product erasure action (calls DELETE /v1/auth/me).
  • Transactional email: by signing up you accept service emails (account verification, password reset, security alerts). Marketing emails (if introduced later) will be opt-in only.

4a. Notifications & alerts

You can choose to receive alerts — including browser ("web push") notifications — that tell you when a statistical pattern you follow appears in a match. Alerts are optional: you turn them on yourself and can turn them off at any time in your account settings or by revoking notification permission in your browser. How we handle the data behind push notifications is described in our Privacy Notice (§6a).

An alert is a factual, statistical observation — the same kind of information-only content described in §3 above. It is not a betting tip, a recommendation, a prediction, or any instruction to place a wager, and it never includes raw or live odds, betting tips, or "sure" picks. Any use you make of an alert in connection with a wager is entirely your own decision and your own responsibility.

5. Subscription tiers

Letguru offers a free tier available to anyone who creates an account, and one paid tier introduced at public launch. Both tiers grant access to the same service classification described in §3; the paid tier unlocks expanded analytics, history, and notification features.

Pricing, billing intervals, and payment processors are published on the pricing page when the paid tier becomes available. Prices are shown exclusive of VAT; any applicable VAT is calculated and added at checkout, and the VAT-inclusive total is shown before you confirm payment. Invoices are issued in compliance with Romanian tax rules and Directive 2006/112/EC.

5a. Auto-renewal & cancellation

Paid-tier subscriptions are sold on a recurring basis. Unless you cancel, your subscription renews automatically at the end of each billing period — monthly or annual, as selected at checkout — for a further period of the same length, and the payment method on file is charged the then-current price for that tier. The recurring nature of the charge, the renewal price, and the billing interval are disclosed clearly and prominently at the point of sale on the pricing page before you confirm, as required by Romanian consumer-protection law (OUG 34/2014) and EU Directive 2011/83/EU Art. 6.

You can cancel at any time, with no cancellation fee, from your account settings or by emailing support@letguru.app. Cancellation takes effect at the end of the billing period you have already paid for: paid access continues until then, after which the account reverts to the free tier. If we change the renewal price, we notify you by email at least 30 days beforehand (see §14) so you can cancel before the new price applies.

5b. Token purchases

Some features are accessed using tokens — a prepaid unit you buy in advance and use to perform specific actions in the product, such as running an analysis or unlocking expanded statistical history. The price of a token and the number of tokens each action uses are shown before you buy or spend them. Tokens pay for access to information-only analytics features (§3); they are not tied to any wager, outcome, or financial return.

Tokens are a product-access unit only. They have no cash value, are not money, a deposit, or a stored-value instrument, earn no interest, and cannot be transferred, resold, or exchanged for cash. A token is treated as fully used once the action it pays for has been performed; consistent with EU Directive 2011/83/EU Art. 16(a) on fully-performed digital services, a spent token is non-refundable, without prejudice to the mandatory statutory rights in §6 and §6a. Unspent tokens stay usable for as long as your account is open.

6. Right of withdrawal (paid tier only)

If you subscribe to the paid tier as a consumer based in the EU/EEA, you have a 14-day right of withdrawal under EU Directive 2011/83/EU and Romanian law (OUG 34/2014), starting on the day the contract is concluded. You may exercise this right by emailing support@letguru.app with a clear statement of withdrawal. We refund the full fee within 14 days of receipt.

Consumers based outside the EU/EEA (e.g. UK, Switzerland) may have analogous statutory withdrawal rights under their own national consumer-protection law; those rights apply directly to your contract regardless of this clause, as preserved by Rome I Regulation Art. 6.

Loss of withdrawal right: if you expressly request that the paid service start during the 14-day window and acknowledge that the right of withdrawal is lost upon full performance, you waive withdrawal once the service has been fully performed (per Dir. 2011/83/EU Art. 16(a)).

6a. Refund policy

This section summarises when fees are refundable; it does not limit your stronger statutory rights under §6 (withdrawal) or §13 (termination):

  • 14-day withdrawal: EU/EEA consumers may withdraw within 14 days of purchase for a full refund, except where the withdrawal right has been lost under §6 (paid service expressly started and fully performed within the window).
  • Subscriptions: outside the withdrawal window, a billing period already started is non-refundable. Cancelling stops future renewals but does not refund the current period. If we terminate your account without material breach on your part, the unused remainder of the paid period is refunded pro-rata (§13).
  • Tokens: unspent tokens bought within the last 14 days may be refunded on request under §6. Tokens already spent are non-refundable as fully-performed digital services (§5b).
  • How to request: email support@letguru.app with your account email and the charge concerned. Approved refunds are returned to the original payment method within 14 days.

7. Acceptable use

  • Letguru is an information-only product. Not betting advice.
  • One account per person.
  • No scraping, automation, or commercial redistribution of the data.
  • The service is provided AS-IS — outages, regressions, and changes can happen.
  • By signing up you accept transactional emails (verify, security alerts).

8. Prohibited conduct

You agree not to:

  • Scrape, mirror, frame, or systematically harvest content from letguru.app.
  • Use bots, scripts, or non-human means to interact with the service.
  • Resell, sublicense, or commercially redistribute letguru content or output.
  • Reverse-engineer, decompile, or attempt to derive proprietary algorithms from the service, except to the extent expressly permitted by Romanian Law 8/1996 Art. 76–78 (interoperability) and EU Directive 2009/24/EC.
  • Bypass authentication, rate-limits, or anti-abuse mechanisms (e.g. Turnstile).
  • Use letguru in ways that violate gambling, advertising, consumer-protection, or data-protection laws of your jurisdiction.
  • Impersonate another person or misrepresent your identity.

9. Intellectual property

All software, copy, branding, statistical analyses, and derived datasets on letguru.app are owned by ALANDALA SOFTWARE SOLUTIONS SRL or its licensors. Underlying raw match results are public-domain facts; our compilation, scoring, and presentation of those facts are protected as a database under EU Directive 96/9/EC and as software under Romanian Law 8/1996. You receive a limited, revocable, non-transferable, non-exclusive license to view and personally use the service while these terms are in force.

10. Data and privacy

Our handling of your personal data is governed by the Privacy Notice, which incorporates by reference into these terms. The Privacy Notice describes what we collect, why, how long we keep it, and how to exercise your GDPR rights.

11. Disclaimer of warranties

Letguru is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, including (without limitation) merchantability, fitness for a particular purpose, accuracy of any statistical output, or non-infringement. Statistical models do not guarantee outcomes. Where mandatory consumer-protection law grants you warranty rights that cannot be waived, those rights are unaffected by this clause (Romanian Civil Code Art. 1707 et seq.; EU Directive 2019/771 on the sale of goods, CELEX 32019L0771, as transposed into Romanian law by Law 449/2003 with the amendments of Law 72/2022; and Directive 2019/770 on digital content and services).

12. Limitation of liability

To the maximum extent permitted by Romanian and EU law:

  • For the free tier, our aggregate liability for any claim arising from your use of the service is limited to the minimum permitted by applicable law, including (without limitation) Romanian Civil Code Art. 1355, OG 21/1992 on consumer protection, and any mandatory non-waivable consumer rights of your habitual residence.
  • For the paid tier, our aggregate liability for any claim is limited to the fees you paid us in the 12 months preceding the event giving rise to the claim.
  • We are not liable for indirect, incidental, consequential, special, or punitive damages, including loss of profits, betting losses, lost data, or business interruption.

None of these limitations exclude liability for death or personal injury caused by our negligence, for fraud, or for any other liability that cannot be excluded under applicable law.

13. Termination

Termination by you: you may close your account at any time via the in-product erasure action. Your account row + all linked auth artefacts are hard-purged within 30 days of the erasure request, in line with GDPR Art. 12(3) (see the Privacy Notice §6 retention timeline and §7 rights).

Termination by us: we may suspend or terminate your account, with or without notice, for breach of these terms, fraud, abusive behaviour, prolonged inactivity, or for legal or operational reasons. Prepaid paid-tier fees for the unused remainder of the billing period will be refunded pro-rata unless termination is for material breach.

14. Modifications

We may update these terms by posting a revised version on this page and bumping the "Last updated" date above. Material changes (e.g. new fee structures, new prohibited conduct, changes to dispute resolution) will be notified via the email address associated with your account at least 30 days before they take effect; continued use after the effective date constitutes acceptance. If you do not accept the change, you may delete your account before the effective date.

14a. Force majeure

Neither party is in breach of these terms for any failure to perform caused by circumstances beyond reasonable control, including (without limitation) natural disasters, war or civil unrest, infrastructure or upstream-provider outages, state-mandated suspensions, malicious third-party attacks, or changes in applicable law that prevent provision of the service. The affected party must notify the other within 5 business days of becoming aware of the event. If the force-majeure event persists for more than 30 consecutive days, either party may terminate the paid-tier subscription with no refund obligation for the period during which the service was unavailable due to the event, without prejudice to your mandatory pro-rata refund rights under applicable consumer-protection law.

15. Governing law and jurisdiction

These terms are governed by Romanian law, without prejudice to the mandatory consumer-protection rules of the EU member state where the user has their habitual residence (Rome I Regulation Art. 6).

The competent courts of Bucharest, Romania have non-exclusive jurisdiction over disputes arising from these terms. EU-resident consumers may also bring proceedings before the courts of their member state of residence (Brussels I bis Regulation Art. 18).

16. Online dispute resolution

The European Commission provides an online dispute resolution platform at ec.europa.eu/consumers/odr. We are not currently obliged or willing to participate in dispute-resolution proceedings before a consumer arbitration board, but you may use the ODR platform to notify us of a dispute.

17. Severability, assignment, survival, entire agreement

Severability. If any provision of these terms is held unenforceable, the remaining provisions remain in full force.

Assignment. We may assign these terms and our rights and obligations hereunder to a successor entity in connection with a merger, acquisition, corporate reorganisation, or sale of all or substantially all of our assets, without your prior consent. Such assignment will be notified to you per §14. You may not assign your rights or obligations under these terms without our prior written consent.

Survival. Sections 9 (Intellectual property), 11 (Disclaimer of warranties), 12 (Limitation of liability), 15 (Governing law and jurisdiction), 16 (Online dispute resolution), and this §17 survive termination of these terms.

Entire agreement. These terms, together with the Privacy Notice and the Imprint, constitute the entire agreement between you and letguru concerning the service, and supersede any prior agreements.
