DataLottoLegal notice and terms of use
1. Owner
In accordance with Spanish Law 34/2002 on Information Society Services and Electronic Commerce (LSSI-CE), the website data-lotto.com and the DataLotto app are owned by Roberto Ruiz, resident in Spain.
- Contact email: [email protected]
2. What DataLotto is
DataLotto is a free tool for statistical analysis, generation and organisation of lottery combinations, for entertainment and information purposes.
DataLotto does not sell tickets, does not handle bets and does not pay out prizes, and it is not a gambling operator.
3. No affiliation with the game operators
DataLotto is an independent project. It is not affiliated with, sponsored by or endorsed by Sociedad Estatal Loterías y Apuestas del Estado (SELAE), nor by the operators of EuroMillions, Powerball or Mega Millions.
The names of the games (Primitiva, Bonoloto, El Gordo, EuroMillions, EuroDreams, Lotería Nacional, Powerball, Mega Millions) are trademarks of their respective owners and are used only to identify the game the data refers to.
4. Terms of use
- DataLotto is intended only for people aged 18 or over. These terms are accepted when you first open the app and are requested again whenever they change.
- Draws are random: every combination has the same probability and every draw is independent of the previous ones. No statistic, filter or system increases the probability of winning.
- Reduced systems offer conditional guarantees: they only apply if the winning numbers are among those chosen by the user. They require fewer bets than the full system, in exchange for less coverage.
- Results, jackpots and statistics are shown for information purposes and may contain errors or delays. Always check your tickets against official sources.
- Users are solely responsible for their gambling decisions. The owner is not liable for financial losses arising from the use of the app.
DataLotto can make mistakes. Although it is carefully reviewed, it is not infallible. There may be errors in mathematical calculations, draw histories, jackpots, dates or any other information. Use DataLotto as an aid, not as a definitive source: always check important data against official sources before making any decision. If you spot an error, you can report it through the app's contact form.
5. Responsible gambling
Only play with money you can afford to lose, and never to win back losses. If gambling stops being fun, ask for help. It is free and confidential:
- Spain: jugarbien.es, the responsible gambling website of the Spanish Directorate General for Gambling Regulation. FEJAR helpline (Spanish Federation of Rehabilitated Gamblers): 900 200 225, free and anonymous.
- United States: National Problem Gambling Helpline, call or text 1-800-MY-RESET (ncpgambling.org).
- United Kingdom: National Gambling Helpline (GamCare), 0808 8020 133, 24 hours (gamcare.org.uk).
- Rest of the world: Gambling Therapy, free online support in more than 40 languages.
6. Intellectual property
DataLotto's code, design, texts, icons and reduced-system matrices are the property of the owner. Reproduction, distribution or modification without express permission is prohibited, except for personal use of the app.
7. Availability and links
The owner aims to keep the app running continuously but does not guarantee that it will be free of interruptions or errors. Links to third-party websites are provided for convenience only; the owner does not control and is not responsible for their content.
8. Governing law
These terms are governed by Spanish law. Any dispute will be heard by the courts that have jurisdiction under the applicable rules, including consumer protection rules.
Privacy policy
1. Data controller
Roberto Ruiz, owner of DataLotto, resident in Spain. Contact: [email protected]
This policy complies with Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018 (LOPDGDD).
2. What data is processed and why
DataLotto is designed so that almost everything stays on your device.
2.1 Data that stays only on your device. Your tickets and their history, your saved filters, language and theme, the copy of the draw histories and the app files needed to use it offline. Also the record that you accepted the terms of use, with a code generated on your device. None of this is sent to the owner or to third parties.
2.2 Usage statistics without identifiers. When you save or check a ticket, the app sends DataLotto's server data such as: game, bet type, number of combinations, matches obtained, draw date and numbers marked as favourites. It is stored in a spreadsheet owned by the owner (Google Sheets). It does not include any user or device identifier, and is only used to understand how the app is used overall.
2.3 Contact form. If you write to the owner from the app, your message and, if you provide it, your email address are sent. They reach the owner as a Telegram message and are used only to reply to you.
2.4 Internal prize alerts. When a checked ticket wins a significant prize, the owner receives a Telegram alert with the game, bet type and matches, without any data identifying who played it.
2.5 Technical connection data. As with any website, your IP address and basic browser data reach the providers that serve the app: Cloudflare (the website) and Google (the server and the spreadsheets with the draw results). DataLotto's server keeps the IP only in memory and for a few minutes, to prevent abusive submissions; it does not store it or link it to any other data. Visits are measured with Cloudflare Web Analytics, which does not use cookies or identify visitors.
2.6 Advertising. DataLotto does not currently show advertising. If it is enabled in the future, your consent will be requested first and this policy will be updated with full details.
3. Legal basis
| Processing | Legal basis |
|---|---|
| Data on your device (2.1) | Necessary to provide the service you request (Art. 6(1)(b) GDPR) |
| Statistics without identifiers (2.2) and internal alerts (2.4) | Legitimate interest in improving the app, with minimised data (Art. 6(1)(f) GDPR) |
| Contact form (2.3) | Your consent when you send it (Art. 6(1)(a) GDPR) |
| Technical data and security (2.5) | Legitimate interest in serving the website securely (Art. 6(1)(f) GDPR) |
4. Recipients and transfers
Data is only shared with the providers that run the app: Cloudflare, Inc. (website hosting and visit measurement), Google (server, Google Sheets and Apps Script) and Telegram (receiving contact messages and alerts). Some of them may process data outside the European Economic Area; in that case they do so with the safeguards provided for in the GDPR, such as the EU-US Data Privacy Framework or standard contractual clauses.
The owner does not sell or share your data with third parties.
5. Retention
- Data on your device: until you delete it (by clearing the site data or uninstalling the app).
- Statistics without identifiers: indefinitely, as a historical usage series.
- Contact messages: as long as needed to handle your request and at most one year after the last contact.
- IP on the server: a few minutes, in memory only.
6. Your rights
You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to [email protected]. As most data stays only on your device or does not identify you, you can often exercise them yourself by deleting the app's data.
If you believe your rights have not been respected, you can lodge a complaint with the Spanish Data Protection Agency (aepd.es) or with the data protection authority of your country.
7. Minors
DataLotto is intended exclusively for people aged 18 or over and does not knowingly collect data from minors.
8. Security
All of the app's communications are encrypted (HTTPS). Even so, no system is infallible: do not include sensitive information in the contact form that is not necessary.
9. Changes
This policy will be updated when the app or the law changes. Significant changes will be announced within the app.
