Privacy Notice

When you use the Nerdle solver, the equations and tile feedback you enter are sent to the same NerdleBuddy application so it can validate the rows and rank suggestions. When you play a puzzle, guesses are sent to the application for scoring and hints.

NerdleBuddy does not deliberately add those equations, answers, feedback patterns, or encoded challenge values to analytics events. They may still pass through ordinary application infrastructure needed to answer the request, including transient network processing and operational logs.

The solver and guides work without signing in. When accounts are enabled, guests can play up to five games a day. A free account removes that limit and enables saved progress across devices and social features. Where accounts are enabled, signing in uses Google sign-on only: NerdleBuddy stores the name, email address, and profile image that Google provides, plus the timestamps of your account and sign-ins. NerdleBuddy never sees your Google password and does not request access to anything else in your Google account.

Signing in sets session cookies on nerdlebuddy.com so you stay signed in; they are functional cookies, not advertising identifiers. Account details are held in NerdleBuddy’s own database and are not sold or shared for advertising.

While you are signed in, finishing a puzzle saves a game record — which puzzle, your guesses, the outcome, whether hints were used, and when you finished — to power your private history, stats, and streaks on the profile page. Saving a game also stores your browser's IANA time-zone name (for example "Europe/London") with your account so streaks and the daily turnover follow your local calendar; it is never your precise location and is deleted with your account. While a game is still in progress, the guesses you have played so far are also saved to your account so the same board can be picked up on another device; that in-progress copy is cleared when you finish. Signed-out play can create a guest account and save game records, as described below. These records are private to your account and are removed when you delete it.

If you play a daily puzzle in ranked mode, NerdleBuddy also stores that attempt's server-scored board with your account — each guess together with the time it was played; this ranked history is private to you and is deleted with your account.

Play preferences you set are stored with your account so they follow you across devices — the "No spoilers / hints" switch and its assisted-input check from the settings, the light or dark appearance you choose, and the board theme you equip on the rewards page. They are simple setting values, never personal information, and they are deleted with your account; without an account the same choices are kept only in this browser. If you use the spoiler shield, the answers you explicitly reveal on dated puzzles (which puzzle and when) are also stored with your account so every device can mark a later solve as a replay; these reveal marks are deleted with your account too.

Finishing a puzzle without signing in creates a lightweight guest account so your points and streaks persist — it stores only the games you finish, no name or email address. Guest data that never records a game is deleted after 30 days, and dormant guest data after 180 days. Signing in with Google moves everything to your permanent account.

Finished games earn on-site points and XP, and so do guide-reading rewards, buried-treasure finds, and a small once-a-day return bonus. NerdleBuddy stores your balance and a private ledger of each award (what kind of award, its amounts, and when — including which guides you claimed, which treasures you found, and which days the return bonus was paid) so totals stay accurate and can be audited. Coins you spend in the on-site shop — streak freezes and board themes — are recorded in that same private ledger; owning a theme is simply its purchase entry there. Your player tier and its earning bonuses are derived from that same activity — lifetime points, recent play days, streaks, and recent referrals — plus one anonymous comparison of your recent totals against overall player activity; no other player's individual activity is ever shown to you, and yours is never shown to them. Points and XP have no monetary value, cannot be purchased or transferred, are visible only to you, and are permanently removed with your account.

If you use friends or buddy groups, NerdleBuddy also stores the display name (handle) you choose, your friend connections and requests (who and when), which groups you belong to, and the kudos you send and receive (sender, recipient, emoji, and day), plus the text you post on a friend's activity wall and the streak nudges you send (sender, recipient, and day). Friends see you by your full name or display name — never your email — and display names and group activity are visible only to your friends and the members of your groups, never on public pages; all of it is deleted with your account or when you leave a group. The member who owns a group can also delete the whole group, which removes the group, its join code, and every member's membership record at once, or remove a single member, which removes only that member's membership record; each member's own games, points, and kudos stay on their account. Guests cannot use friends or groups; a Google account is required because these surfaces show names.

If you turn on the public leaderboard in your profile settings, your display name and your standings (puzzles solved and current streak, derived from your saved game records) appear on the leaderboard page — visible to anyone — until you turn it off; never your email, full name, or photo. NerdleBuddy stores that choice and its date with your profile. If you report a leaderboard row, it stores who you reported, the day, and the fixed reason you picked; a moderator can hide a player from the boards, which stores only a hidden-since date and changes nothing else about their account. All of it is deleted with your account.

Every account can create a shareable referral code. If someone signs up through your code, NerdleBuddy stores who referred whom, the code used, and the date, and shows you the new player's display name or first name with that date on your profile. Referrers also earn bonus points calculated as a percentage of the points their referred player earns during that player's first six months, which means a referrer can see the total bonus each referred player has generated (an aggregate of their activity, never individual games). Opening a referral link stores the code in your own browser until you sign up, claim its welcome points, or clear your browsing data — no account is created just by visiting. All referral records are deleted when either account is deleted.

Sharing a finished puzzle can create a challenge link: NerdleBuddy stores a random link token, which puzzle it belongs to, and the score from your own recorded game, plus the score of each signed-in player who finishes the puzzle through your link. Whoever opens the link sees only your display name or first name with the score — never your email or account details — and you see the same for players on your challenges (players without a name appear anonymously). Challenge records are deleted with your account.

If you turn on streak reminders, NerdleBuddy stores the push subscription your browser creates — an address supplied by your browser's push service (Apple, Google or Mozilla), plus the two keys needed to encrypt a message to it. It is used for one thing: a single evening reminder when your streak is live and you have not finished that day's puzzle. Nothing else is ever sent. Turning the toggle off, revoking notification permission, or deleting your account removes the subscription, and an address the push service reports as gone is deleted automatically.

You can sign out at any time, and the profile page includes a self-service delete that permanently removes the account record and its sign-in link.

This deployment uses Google Analytics through its own script, loaded after the initial page load. It can count solver use, games, hints, answer reveals, filters, shares, guide-to-solver visits, and the navigation timing described below.

Page measurement uses normalised URL shapes. For example, an encoded challenge becomes /nerdle/buddy/puzzles/:token and a dated archive game becomes /nerdle/buddy/puzzles/date/:date. Query strings and the original values are not sent in the custom analytics payload.

Cloudflare Web Analytics measures page views and loading performance through a browser beacon. Those measurements are separate from NerdleBuddy's custom Google Analytics events.

When Google Analytics is configured, we also send page transition durations, the navigation method, and fixed page categories. These events exclude full URLs, query strings, exact puzzle dates, and account or group identifiers.

NerdleBuddy does not currently provide an in-app analytics consent prompt or consent management platform. Analytics and consent obligations vary by location. The Google Analytics measurement ID should remain unset wherever prior consent is required until an appropriate consent solution, vendor disclosures, and retention settings are in place.

The site uses local browser storage for the on-screen keyboard preference, commutative-answer grouping, probe suggestions, and optional feedback prefill. These values describe settings, not your identity. Hint visibility is kept only in page memory and resets on a fresh load.

Clearing NerdleBuddy site data resets local preferences and signs you out. If Google Analytics is configured, Google may use cookies or browser identifiers according to the analytics configuration. NerdleBuddy does not currently offer an in-app control for those tags.

NerdleBuddy is hosted on Cloudflare, which delivers the site and caches public pages and assets. Hosting infrastructure can process request information such as IP address, user agent, route, timestamps, and error details for delivery, security, and operational logging.

Optional Google measurement uses Google Analytics directly. Verified official answers are fetched and cached on NerdleBuddy's servers; opening an answer page does not make your browser fetch that source page.

You can clear nerdlebuddy.com site data in your browser, block cookies or scripts, use browser tracking protection, and leave optional fields unused. Blocking measurement does not prevent the core solver, guides, or games from working, although strict script blocking can affect interactive features.

For a non-personal correction, you can open an issue in the NerdleBuddy project repository. Do not post personal or confidential information in a public issue. For private questions, use the contact information on the About page.

Account details, sessions, and game records are kept for as long as your account exists. Deleting your account permanently removes the account record, its sign-in link, active sessions, and every game record tied to it. Expired sessions, sign-in verification entries, and rate-limit counters are transient operational data with no long-term retention purpose. Ordinary infrastructure logs and backups held by our providers age out on their own schedules.

Depending on where you live (for example under the GDPR in Europe or the CCPA in California), you may have rights to access, correct, delete, restrict, or receive a copy of your personal data, and to object to certain processing. We honour these in the most direct way available:

• Access & deletion are self-service: your profile page shows what is stored about you and includes a permanent delete-account action — no request form, no waiting period.
• Correction: your name, email, and avatar come from your Google account; updating them there updates what Google provides at your next sign-in.
• Everything else (data export, objections, questions): raise it through the channel on the About page. We do not sell personal data or share it for cross-context behavioural advertising, so there is nothing to opt out of on that front.

You also have the right to complain to your local data-protection authority.

The puzzles and solver are suitable for everyone, but accounts are not directed to children: you must be at least 13 (or your country’s minimum age of digital consent) to sign in, per the Terms of Use. We do not knowingly collect personal data from children below that age; if you believe a child has created an account, contact us and we will delete it.

When the site starts collecting something new — as happened when accounts and game records launched — this notice is updated first and the “last updated” date above changes. Material changes will be visible on this page before they apply to you.
