Privacy Policy
Last updated: 14 September 2026
This policy explains what LogoMapper stores, what third parties are involved, and what control you have. LogoMapper is operated by Jonathan Schuller as an independent project. For visitors covered by the EU or UK General Data Protection Regulation (GDPR), Jonathan Schuller is the data controller for this site, reachable at the contact address at the bottom of this page.
The short version
- There are no user accounts. You are never asked to register or provide a name, email address, or any other personal detail to play.
- Your streak and play history stay in your own browser. Your daily score is sent to the leaderboard, with no name attached — see below.
- Third parties do set cookies — specifically Google, for advertising. That is the main privacy consideration on this site, and it is covered in detail below.
Data stored in your browser
LogoMapper uses your browser's local storage to remember your play history. This is not a cookie. Apart from the leaderboard score described above, none of it is sent anywhere — it stays on your device. The stored values are:
| What is stored | Why |
|---|---|
| Your results for each daily mode | To show your summary if you revisit after playing, and to prevent replaying a day's round |
| Your daily streak | To display consecutive days played |
| Whether you dismissed the instructions | So the help panel doesn't reappear every visit |
| Your sound effects on/off setting | So the sound toggle in the menu remembers your choice |
| An anonymous leaderboard ID | A random value so the board can recognise your own row. Not linked to any name or account |
Because this data lives only in your browser, it is per-device: your streak on a phone is separate from your streak on a laptop. Clearing your browser's site data for logomapper.gg will permanently erase your history and streak, and there is no way to recover it — the only copy was the one on your device.
The daily leaderboard
When you finish a daily round, your score is sent to the leaderboard so it can tell you where you placed and show the day's top ten. This is the only thing on the site that leaves your browser.
What gets sent:
| Sent | Why |
|---|---|
| Your total score and your five per-question scores | To rank you and to fill in the Q1–Q5 columns on the board |
| An anonymous ID | A random number generated by your browser, so the board can stop one browser submitting twice and can highlight your own row |
| The date and game mode | To put the score on the right day's board |
No name, no email, no account. The anonymous ID is a random value created in your browser — it is not derived from your device, and it identifies a browser profile rather than a person. Clearing your site data replaces it with a new one.
Leaderboard scores are deleted automatically after 30 days. Your IP address is not stored with your score, though as with any web request it appears briefly in server logs.
There is no way to opt out of the leaderboard while still playing the daily game, because the score submission is what produces your rank. If you would rather not appear at all, Endless mode has no leaderboard and submits nothing.
Advertising — Google AdSense
LogoMapper displays ads served by Google AdSense. This is how the site is funded. The site also runs advertising campaigns through Google Ads, and uses the Google tag (gtag.js) to measure whether those campaigns lead to visits — called conversion measurement. In the EEA, the UK and Switzerland this measurement follows the same consent choice you make in the consent message described below.
- Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visits to LogoMapper and elsewhere on the internet.
- Third-party vendors, including Google, may show LogoMapper's ads on sites across the internet.
You can control this directly:
- Opt out of personalised advertising in Google Ads Settings.
- Opt out of some third-party vendors' use of cookies at aboutads.info/choices.
- Read how Google uses information from sites that use its services.
If you are in the EEA, the UK or Switzerland, a consent message is shown before ads may use your data. It is Google's certified consent management platform, integrated with the IAB Transparency and Consent Framework, and the choice you make in it governs how your data is used for advertising on this site. The legal basis for advertising cookies is your consent, and you can change or withdraw it at any time:

Analytics — Cloudflare Web Analytics
LogoMapper uses Cloudflare Web Analytics to count visits. It is deliberately chosen because it is privacy-first: it sets no cookies, does not fingerprint visitors, and does not track people across sites. It reports aggregate figures such as page views and country of origin. It cannot identify you individually, and there is no cross-site profile.
Other third-party services
| Service | Purpose | Data involved |
|---|---|---|
| Google AdSense | Advertising | Cookies, ad identifiers, IP address |
| Google Ads (Google tag / gtag.js) | Measuring whether ad campaigns lead to visits | Cookies, ad identifiers, IP address — consent-gated in the EEA/UK/Switzerland |
| Cloudflare Web Analytics | Visit counting | Aggregate only, no cookies |
| unpkg (CDN) | Serves the globe rendering library | Your IP address, as with any file request |
| Esri | Satellite map imagery on the globe | Your IP address, as with any file request |
| Amazon CloudFront / S3 | Hosts the site itself | Standard server access logs |
| Amazon API Gateway / DynamoDB | Stores daily leaderboard scores | Score, anonymous ID, date. Deleted after 30 days |
Any service that sends you a file necessarily receives your IP address — that is how the web works. Server access logs are retained for operational and security purposes such as diagnosing faults and detecting abuse, and are deleted automatically after 12 months.
Legal bases for processing (EEA and UK visitors)
Where the GDPR applies, the legal bases for the processing described above are:
| Processing | Legal basis |
|---|---|
| Advertising cookies and personalised ads (Google AdSense) | Consent (Art. 6(1)(a)), given or refused in the consent message and withdrawable at any time via the link above |
| The daily leaderboard (score, anonymous ID, date) | Legitimate interests (Art. 6(1)(f)) — operating the ranking feature that finishing a daily round invokes, with minimal data and 30-day deletion |
| Server access logs (IP addresses) | Legitimate interests (Art. 6(1)(f)) — site security, abuse detection and fault diagnosis |
The play history, streak and settings kept in your browser's local storage are not sent to us at all. That storage is strictly necessary for features you actively use, which is the category the EU ePrivacy rules exempt from consent requirements.
International transfers
The third-party providers named above — Google, Cloudflare and Amazon Web Services — are US companies, so data they receive (such as your IP address) may be processed in the United States. Each of these three is certified under the EU-U.S. Data Privacy Framework, the mechanism under which the European Commission recognises transfers to participating US organisations as providing adequate protection. Esri, which serves the globe's satellite imagery directly to your browser, handles requests under its own privacy statement.
Your rights (EEA and UK visitors)
Where the GDPR applies, you have the right to access, rectify, erase, restrict, or object to the processing of your personal data, the right to data portability, the right to withdraw consent at any time (without affecting the lawfulness of processing before the withdrawal), and the right to lodge a complaint with your data protection supervisory authority.
A practical note on exercising them here: this site holds nothing that identifies you — no name, email, or account — so most stored data cannot be linked to a person by us or anyone else. The one server-side record is your leaderboard row, keyed only by the random ID in your browser. If you want a leaderboard entry deleted before its automatic 30-day expiry, include that ID (visible in your browser's site data for logomapper.gg) in your request so the row can be found.
Children
LogoMapper is not directed at children under 13 and does not knowingly collect personal information from them. Since the site has no accounts and collects no personal details, there is nothing for a child to submit.
Your choices
- Erase your history: clear site data for logomapper.gg in your browser settings. This removes your local scores and streak immediately and permanently. Scores already on a leaderboard stay until they expire after 30 days, but nothing connects them to you.
- Change or withdraw advertising consent (EEA, UK, Switzerland): use the "change or withdraw" link in the Advertising section above to reopen the consent message at any time.
- Block advertising cookies: use your browser's cookie controls or the Google opt-out links above. The game itself works fine without them.
- Play without local storage: the game still runs, but your streak and results will not be remembered between visits.
Changes to this policy
If this policy changes materially — for example if a new third-party service is added — the "last updated" date above will change. Since there are no accounts, there is no way to notify you directly, so this page is the record.
