Solveville Privacy Policy

Effective date: September 28, 2026

1. Overview

This Privacy Policy explains what information DB Performance Inc. ("DB Performance," "we," "us") collects when you use Solveville, our puzzle-game app at play.solveville.com (the "App"), how we use it, and the choices you have. It is part of our Terms of Service.

The short version: we collect only what the App needs to work — your email address to sign you in, a display name for each player profile, gameplay data so progress syncs across devices, and a payment record from Stripe if you buy a license. We do not show ads, we do not sell or rent your information, we do not use third-party advertising or analytics trackers, and we do not knowingly collect personal information directly from children.

2. Information we collect

Account information. When you create an account we collect your email address. There is no password: we sign you in with a one-time link sent to your email, or through Google if you choose, in which case we receive your email address and a Google account identifier. We also record that you confirmed you are 18 or older and which version of the Terms you accepted.

Player profiles. Each account can have up to four player profiles (one on the Single plan). A profile has a display name you choose (a first name or nickname is enough — we do not ask for a full name, age, or birthdate) and optional settings such as a chosen avatar or relaxed-mode preferences.

Gameplay data. For each profile we store the levels started and completed, scores, stars, best times, coins and boosters earned and spent, hints used, per-game statistics, and in-progress level state so you can resume where you left off. This data is tied to the account and profile, not to any real-world identity beyond the account email.

Purchase information. If you buy a license (Single or Family), our payment processor Stripe collects your card details directly. We never see or store your full card number. We receive and keep a record of the transaction: the amount, date, currency, the last four digits and brand of the card, your billing email, the Stripe customer and payment IDs, and the status of any refund or dispute.

Gifts. If you buy a gift, we collect your email address (to send you the gift code and receipt) and, if you add them, the recipient's name and a short message, which are printed on the gift card. We keep these with the gift's payment record. A gift card can be opened only through the private link we send you. When a gift code is redeemed, we record which account redeemed it; if the gift is later refunded or disputed, we email that account to say why its access ended.

Technical and usage information. When you use the App our servers and hosting provider automatically receive standard technical data: your IP address, browser type and version, device type and operating system, screen size, language, the pages and game screens you load, and timestamps. We use this for security, to enforce your plan's device limit, to keep the App running, and to understand which games and levels are being played. We also record login events (time, IP address, and a device identifier we generate) to detect account sharing and unauthorized access.

Support communications. If you email us, we keep the email and any information you include so we can respond and keep a record of the request.

Beta survey. If you answer the survey at /survey, we receive your answers (about your family's use of the games, your children's age ranges, and your opinions), an email address only if you give one, and your browser type and screen size. We use it only to improve the games and pricing. It asks for no names.

Problem reports. If you use the 🐞 Report a problem button, we receive what you type, the reply email address if you give one, and details about the screen at that moment so we can find and fix the problem: which screen and game were open, the level and its in-progress state, the device, browser, screen size and language, recent error messages from the App, the last few screens visited, and (unless you untick it) a small picture of the game board. Player names are not included. Reports are sent only when you press Send, are used only to fix problems, and are visible only to the App's administrator.

Free daily puzzle. The puzzle at /daily needs no account and collects nothing: no sign-in, no forms, no ads and no trackers, and nothing about the player is sent to us. The only thing it keeps is on your device (the last day solved, its result and the streak, in your browser's storage). As with any web page, our hosting provider receives the standard technical data described above when the page loads.

Show a friend. The summary on a player's Stats page (their first name, how many puzzles they have solved, and their streak) is put together on your device and is sent only by you, with your own app, after you have read and edited it. We do not receive or store it.

We do not collect precise location, contacts, photos, microphone or camera data, or any information from other apps on your device.

3. How we use information

We use the information above to:

• create and secure your account, sign you in, and enforce the one-trial rule and your plan's player and device limits;
• save and sync gameplay progress, coins, boosters, and settings across your devices, including uploading progress made offline;
• process your purchases, renewals, upgrades, and promotional codes, remind you in the App when your year is ending, and handle refunds, disputes, and receipts;
• respond to support requests and notify you about your account, purchase, or material changes to the App or these policies;
• understand how games and levels are played (for example, which levels are hardest, how long players take, and where they stop) so we can balance difficulty, fix bugs, and decide what to build next;
• monitor for cheating, trial abuse, account sharing, fraud, and security threats;
• keep records we need for tax, accounting, and legal purposes.

We do not use your information for advertising, we do not build advertising profiles, and we do not use automated decision-making that has legal or similarly significant effects on you. We will only send you marketing email (for example, news about new games) if you opt in, and every such email will include an unsubscribe link.

4. Who we share information with

We do not sell, rent, or trade your personal information, and we do not share it with advertisers or data brokers. We share it only as follows.

Service providers that run the App. These companies process data on our behalf, under contracts that limit their use of it to providing their service to us:

Legal reasons. We may disclose information if required by law, subpoena, or court order; to enforce our Terms; to investigate fraud, cheating, or security issues; or to protect the rights, property, or safety of DB Performance, our users, or others.

Business transfers. If DB Performance is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you before your information becomes subject to a different privacy policy.

With your consent. We may share information for any other purpose you agree to at the time.

Other players. Nothing about your account or profiles is visible to other users. The App has no chat, friend lists, public leaderboards, or user-generated content.

5. Children's privacy

Solveville is designed for families, and children are welcome to play on a profile under a parent's or guardian's account. We have built the App so that we do not need to collect personal information directly from children:

• only adults (18+) can create an account, start a trial, or make a purchase;
• child profiles are created and controlled by the adult account holder, hold only a display name chosen by the account holder and gameplay data, and have no separate login, email, or contact information;
• the App has no chat, messaging, user-generated content, social features, advertising, or links to outside sites from within gameplay;
• we do not ask for a child's name, age, birthdate, photo, location, or contact details.

We treat the display name and gameplay data on a child's profile as information collected from the adult account holder, with the account holder's consent. The account holder can delete any profile, and its gameplay data, at any time in the App (Edit players on the Who's playing screen), and can ask us to change or delete any profile by contacting us.

We do not knowingly collect personal information directly from children under 13 (or the applicable age in your jurisdiction) in a way that would require verifiable parental consent under the U.S. Children's Online Privacy Protection Act (COPPA) or similar laws. If you believe a child has given us personal information directly — for example, by creating their own account with their own email — contact us at the address in Section 9 and we will delete the account and its data promptly.

6. Cookies, local storage, and offline play

The App uses a small number of strictly necessary cookies and browser storage items to work. We do not use advertising cookies, third-party analytics cookies, or cross-site tracking.

• Sign-in session. A token that keeps you signed in and identifies your device for your plan's device limit. It expires when you sign out or after a period of inactivity.
• Local game data. Your current profile, settings, and a copy of your gameplay progress are stored on your device so the App loads quickly and so you can play offline. Progress made offline is uploaded to your account the next time you connect.
• Add to Home Screen / offline files. If you install the App to your home screen, your browser stores the App's files on your device so it can open without a connection.
• Stripe. During checkout, Stripe sets its own cookies for fraud prevention, as described in Stripe's privacy policy.

You can clear this data through your browser or device settings. Doing so signs you out and removes locally stored progress; any progress already synced to your account is unaffected. Because these items are necessary for the App to function, there is no separate cookie opt-out. We do not respond to browser "Do Not Track" signals because we do not track users across sites.

7. Retention, security, and where data is stored

Retention. We keep account, profile, and gameplay data for as long as your account exists. If you delete your account, we delete it within 30 days, except for backups (which cycle out within 90 days) and the records below. Trial accounts that never purchase and are inactive for 12 months may be deleted. We keep purchase and refund records for 7 years for tax and accounting purposes, and security and login logs for up to 12 months. Support emails, problem reports and survey answers are kept for 2 years. We may keep a minimal record (such as a hashed email) after deletion to enforce the one-trial-per-person rule and to prevent banned accounts from returning.

Security. We protect your information with industry-standard measures: we never store a password (sign-in uses one-time email links or Google), all traffic is encrypted in transit (HTTPS), data is encrypted at rest by our database provider, and access to production data is limited to the App's administrator over a separate, password-protected admin site. Card data is handled entirely by Stripe, which is PCI-DSS certified. No system is perfectly secure, so we cannot guarantee absolute security; if we learn of a breach affecting your personal information, we will notify you as required by law.

Where data is stored. Our servers and providers are located in the United States. If you use the App from outside the U.S., your information will be transferred to, stored, and processed in the U.S., where privacy laws may differ from those in your country. By using the App you consent to this transfer.

8. Your choices and rights

In the App. Under Edit players on the Who's playing screen you can add player profiles (up to four, or one on the Single plan) and delete them. Deleting a profile permanently removes its gameplay data. To rename a profile, reset its progress, or change your account email, email us at the address below.

Account deletion. You can delete your entire account and all of its data at any time by emailing us at the address below from your account email. We will confirm and complete the deletion within 30 days. Deleting an account does not entitle you to a refund (see the Refund Policy).

Access and correction. You may ask us for a copy of the personal information we hold about you, or ask us to correct it. We will respond within 45 days.

Marketing email. We only send marketing email if you opt in, and you can unsubscribe at any time using the link in the email. We will still send transactional email about your account, purchases, and important changes.

State privacy laws. Residents of California, Colorado, Connecticut, Virginia, Florida, Texas, Oregon, and other states with consumer privacy laws may have additional rights, including the right to know what personal information we collect, to delete it, to correct it, to opt out of its sale or sharing for targeted advertising, and not to be discriminated against for exercising these rights. We do not sell personal information, share it for cross-context behavioral advertising, or use it for profiling with significant effects, so there is nothing to opt out of. To exercise any other right, email us; we may ask you to confirm the request from your account email. If we deny a request, you may appeal by replying to our decision, and we will respond to the appeal within 45 days.

Users outside the United States. If you are in the European Economic Area, United Kingdom, or another jurisdiction with similar laws, our legal bases for processing are performing our contract with you (running the App and your purchase), our legitimate interests (security, fraud prevention, and improving the games), legal obligations (tax records), and your consent (marketing email). You have the rights to access, correct, delete, restrict, port, and object to processing of your data, to withdraw consent, and to lodge a complaint with your local data-protection authority. Contact us to exercise them.

9. Changes and contact

Changes to this policy. We may update this Privacy Policy from time to time. If we make a material change — especially one that expands what we collect or how we share it — we will notify you by email or an in-app notice before it takes effect and update the effective date above. Continued use of the App after the change takes effect means you accept the updated policy.
