Privacy Policy

Effective and last updated: September 30, 2026

Callback AI Solutions Inc., a Delaware corporation (“Interval Games,” “we,” “us,” or “our”), operates the Interval Games mobile app, interval.games, and related daily puzzles, gameplay, progress syncing, and statistics features (the “Service”). This Privacy Policy describes the information we collect, how we use and disclose it, and the choices available to you.

“Personal information” means information protected as personal data or personal information under the law applicable to the processing. Where applicable data protection law requires a controller to be identified, Callback AI Solutions Inc. is the controller for the processing described here. References to particular laws or regional rights apply only where those laws apply to Interval Games and the relevant information.

Privacy contact: support@interval.games. Account deletion: in-app instructions and email requests.

1. Scope and third-party services

This policy applies to the Service, including private testing, and communications with Interval Games. It does not govern app stores, sign-in providers, or other third parties when they process information for their own purposes. Their privacy policies apply to those activities.

The current Service provides personal puzzle play and statistics. It does not offer public player profiles, leaderboards, user posts, comments, or direct messaging between players. Support communications are private inputs to the Service.

2. Information we collect and where it comes from

We collect information you provide, information generated when you use the Service, and information supplied by a sign-in provider you choose to connect. Depending on the features you use, this includes:

• Account information. Player and session identifiers, authentication records, and account dates. The app creates an account even without a name or email address. When Sign in with Apple is available and you choose to use it, we receive the identifiers, name, email address (which may be a private relay address), and authorization information Apple supplies. We do not receive your Apple password.
• Puzzle activity. Games and editions played, saved board states and airport guesses, start and completion times, active play duration, outcomes, and related history and statistics. Statistics such as streaks and average solve times are calculated from these records.
• Support and feedback. Your email address, messages, screenshots, device details, and any other information you choose to include in support requests, privacy requests, or feedback.
• Technical information. IP addresses, request details, device and browser information, operational and security logs, errors, and identifiers used for authentication and abuse prevention. Anonymous-session rate limiting uses a keyed digest derived from the request IP address; infrastructure logs may separately include IP addresses.
• Website analytics. Page visits, browser and device information, referral information, approximate location, and cookie identifiers processed through Google Analytics, as described in section 6. This website integration is separate from the app.

We do not require precise GPS location, address-book contacts, photo-library access, microphone recordings, government identification, or payment-card information to play. Please do not include passwords, session tokens, or unnecessary sensitive information in support requests. Any information you choose to include in a message is processed to handle that communication.

3. How we use information

We use information for the following purposes:

• Provide the Service: create and authenticate accounts, deliver puzzles, save and sync progress, calculate results, and display personal statistics.
• Communicate: respond to support and privacy requests and send service, security, and legal notices.
• Operate and improve: understand website usage, assess service performance, troubleshoot problems, test features, and maintain and secure the Service.
• Protect rights and meet obligations: detect and prevent fraud or abuse, enforce our Terms, comply with applicable law, respond to lawful requests, maintain relevant records, and establish, exercise, or defend legal claims.

We may create and use aggregate or de-identified information for these purposes. Where applicable law requires information to be maintained in de-identified form, we maintain and use it in that form and do not attempt to re-identify it except as permitted by that law, and impose required restrictions on recipients.

4. Puzzle generation and automated processing

Daily puzzles are generated from game rules, edition schedules, and puzzle seeds. Difficulty is configured by day of the week; it is not selected by profiling an individual player. The Service uses saved activity to calculate puzzle outcomes and personal statistics.

Departures uses a prepared catalog of airport and route information. Your airport guesses are puzzle answers, not statements about your actual location, travel plans, or bookings. The app retrieves puzzle and airport information from our service; it does not send your guesses to airlines or route-data providers to perform a travel search.

The current Service does not send player activity to a generative-AI provider for recommendations or chat. We do not use game results to make decisions about credit, employment, insurance, housing, or other matters producing legal or similarly significant effects.

5. Who receives information

We disclose information to the following categories of recipients for the purposes described in this policy:

• Service providers. Providers of hosting, data storage, content delivery, security, diagnostics, analytics, and customer communications. Amazon Web Services hosts the API and database. Cloudflare serves the website and routes support email to our support inbox. Google Analytics processes website usage information. Providers process information needed for their assigned functions, subject to applicable contractual and legal restrictions.
• Sign-in and platform providers. Apple when you use its sign-in service or obtain the app. Apple may also process information independently under its own policies.
• Professional, legal, and security recipients. Advisers, regulators, courts, law enforcement, and other parties when we reasonably believe disclosure is required by applicable law or appropriate to investigate misuse, protect rights or safety, or establish, exercise, or defend legal claims.
• Business transaction participants. Prospective or actual purchasers, successors, investors, advisers, and other participants in a merger, financing, acquisition, reorganization, bankruptcy, or asset transfer, subject to applicable confidentiality and legal requirements.
• Recipients you direct. Other parties when you ask us to disclose information or provide any authorization required for the disclosure.

Authorized personnel may access information in connection with their responsibilities. A complaint or rights request may be shared with the person concerned to the extent needed to address it; correspondence with us is not necessarily confidential from that person.

6. Advertising, sales, and tracking

We do not sell personal information, share it for cross-context behavioral advertising, or use it for targeted advertising. The current app does not use an advertising identifier to build an advertising profile. Website analytics are configured with advertising features and advertising personalization disabled.

The website uses Google Analytics to understand visits, page views, referral sources, and device and browser information. Google uses cookies to distinguish browsers and sessions and receives usage data and technical request information, including IP addresses. This integration covers the public website and is separate from the mobile app. Our configuration sends the initial page URL without its query string or fragment and limits the configured referrer to its origin. We do not configure app account identifiers or puzzle progress as website analytics fields. See How Google uses information from sites that use its services.

You can manage cookies through your browser settings or use the Google Analytics opt-out browser add-on. Analytics cookies remain until they expire or are deleted and may be refreshed on later visits. Analytics records are retained for traffic reporting and analysis according to the applicable retention settings. Clearing cookies does not delete information already collected.

Hosting and security providers process requests and may use technologies needed for delivery and abuse prevention. “Do Not Track” is not a separate feature control. Global Privacy Control and similar opt-out signals do not change our current practice of not selling or sharing information for targeted advertising. These statements concern Interval Games; other third-party sites may have their own tracking practices.

7. External links and information you share

If you follow a link to an external site, that site and its providers may receive your IP address, browser and request details, and cookies applicable to that site. Their policies govern their independent processing.

Your account and puzzle history are not published as a public profile by the current Service. If you independently share a screenshot or result through another app, that app and the recipients control the copies they receive. Deleting an Interval account cannot remove copies held by other people or independent services.

8. Device storage and permissions

The app stores session credentials using iOS secure storage and keeps downloaded puzzles, airport catalogs, cached progress, and pending gameplay updates in a local database. Downloaded puzzles can be played offline; pending updates are sent to our API when connectivity and an authenticated session are available. Some preferences remain on the device.

Device storage and synced server records are separate. Clearing local data or uninstalling the app does not itself delete server-side records and may make an account without connected sign-in unrecoverable. Secure-storage behavior depends on iOS and should not be treated as a guarantee that uninstalling removes every credential. The current app does not request access to contacts, precise location, the microphone, or photo library to play.

9. Retention

Retention depends on the information, the feature, account status, and our operational and legal needs. We consider the time needed to provide the Service, maintain security and recover from incidents, comply with law, resolve disputes, and enforce agreements. Current retention practices include:

• Account and puzzle records: retained to support the account and its features while the account remains available. This includes accounts without connected sign-in. Deletion removes associated records from the active application database as described below.
• Sessions and authentication: retained to manage access and security. Expiration of a credential does not necessarily erase related operational records.
• Backups: routine automated database backups have a 28-day retention window. Deleted records may remain until a backup expires. Separately retained recovery snapshots may last longer for recovery, an incident, or a legal obligation.
• Operational and security logs: application logs are generally retained for one year; infrastructure access logs and replicated copies have lifecycle rules of up to 400 days. Logs may contain request and account-related identifiers.
• Support and legal records: retained as needed to address the matter, maintain records, comply with obligations, and establish, exercise, or defend claims, including applicable limitation periods.
• Puzzles and aviation reference data: shared game content is independent of your account. Account deletion removes your associated attempts, not the published puzzles or airport and route catalogs used by other players.

Retention can be extended for a legal hold, dispute, investigation, security incident, or other applicable legal requirement. Backup and security records are separate from an active player account. When personal information is no longer needed for an applicable purpose, we delete or de-identify it. Independent providers and platforms maintain their own records under their own policies.

10. Account and data deletion

In the app: for an account with connected sign-in, open the settings button in the stats tab and choose Delete account. Confirm while connected to the internet. The current interface does not expose this button for anonymous accounts; contact support for help deleting an anonymous account before removing the app or losing access to its session.

Account deletion removes the account and its associated puzzle attempts, saved game states and guesses, sessions, linked sign-in identity, and stored Apple authorization credentials from the active application database. Personal statistics derived from those attempts are removed with them. The app clears the deleted account’s cached progress as part of its deletion flow. Backups, logs, and retained legal records follow section 9. Deletion does not remove your independent Apple account, shared puzzle content, or copies you have sent to others.

By email: send a request to support@interval.games with the subject “Interval Games account deletion” and the sign-in email or other non-secret account details. We may require verification and may be unable to locate or verify an account without a connected sign-in identity. Never send passwords or access tokens.

Requests to delete particular information are subject to applicable law, verification, and relevant exceptions. Deleting information needed for a feature may prevent its continued operation. Uninstalling the app, signing out, or resetting a board does not submit an account-deletion request.

11. Your controls and requests

You can choose whether to connect Apple sign-in when available, contact support, or share information outside the app. You can manage website cookies through your browser. Resetting local progress does not necessarily erase synced records or prior processing.

To exercise an applicable privacy right, email support@interval.games and describe your request. We may request information to verify identity, authority, residence, or the scope of the request. Never send your password. Requests are subject to applicable eligibility requirements, exceptions, and limits, including protection of others’ information and legal privilege. We may decline a request that cannot be verified or is otherwise exempt, or charge a fee where permitted by applicable law.

We handle requests within the periods required by applicable law, including permitted extensions, and provide notices of decisions or extensions where required. We do not unlawfully discriminate or retaliate for exercising a privacy right. These procedures do not extend a regional statutory right to persons or information outside that law’s scope.

Where processing relies on consent, you may withdraw it through the relevant control or by contacting us. Withdrawal does not affect the lawfulness of prior processing. A feature may be unavailable if it requires the affected information.

12. U.S. privacy rights

Depending on your residence and whether the relevant law applies to Interval Games, you may have rights to confirm processing, access or obtain a portable copy of personal information, correct inaccuracies, delete information, and opt out of sales, targeted advertising, or certain profiling. Some laws also provide rights concerning sensitive personal information. These rights are subject to the conditions and exceptions in the applicable law.

The categories we collect and disclose for business purposes include identifiers and contact information, Internet or electronic activity, puzzle activity and derived statistics, and messages and submissions, as described in section 2. Sources, purposes, recipients, and retention appear in sections 2–5 and 9. Our current practices concerning sales and targeted advertising appear in section 6. Interval Games does not conduct the consequential-decision profiling described in section 4.

You or an authorized agent, where permitted, can use the request procedure above. We may require proof of the agent’s authority and identity verification as allowed by law. If you have a statutory right to appeal a denied request, reply to our decision or email support@interval.games with the subject “Interval Games privacy appeal.” We will provide the response and any regulator-contact information required by the applicable law.

13. EEA, United Kingdom, and Switzerland

This section applies only to processing subject to the relevant data protection law. Depending on the activity, our legal bases are performance of the agreement for account access and requested puzzle features; legitimate interests in operating, securing, maintaining, and improving the Service; compliance with legal obligations; and consent where required. Where legitimate interests are the basis, they are subject to the balancing required by applicable law.

You may have rights of access, correction, erasure, restriction, portability, and withdrawal of consent, subject to statutory conditions and exceptions. You may object to processing based on legitimate interests for reasons relating to your particular situation. Contact us using section 11. You may also complain to the competent supervisory authority, including in your place of habitual residence, work, or the alleged infringement, the UK Information Commissioner, or the Swiss Federal Data Protection and Information Commissioner, as applicable.

Information needed to authenticate a session or provide requested progress syncing is necessary for that function. Optional sign-in and messages depend on your choices. Without information necessary for a feature, we may be unable to provide it.

14. International processing

Interval Games uses infrastructure in the United States. Providers may process information in other countries where they operate, whose privacy laws may differ from those where you live.

Where applicable law requires safeguards for a transfer, the applicable mechanism depends on the provider and destination and may include an adequacy decision or approved contractual safeguards with required supplementary measures. Contact support@interval.games for information about applicable safeguards or a copy where available, subject to lawful confidentiality limits.

15. Security

We use technical and organizational measures designed to protect personal information. No storage system or transmission method is completely secure, and we cannot guarantee against unauthorized access, loss, or other incidents. Protect your device and sign-in credentials and contact us about suspected unauthorized access. We provide incident notices when required by applicable law.

16. Children and teenagers

Interval Games is not directed to children under 13 or a higher minimum age required where they live. We do not knowingly collect personal information from children below the applicable minimum age. Minors must satisfy the age and guardian requirements in our Terms.

If you believe a child has provided personal information contrary to these requirements, contact support@interval.games so we can address the matter, including deletion where required by law.

17. Updates and contact

We may revise this policy as the Service, practices, or legal requirements change. The revised policy will carry an updated effective date. We provide additional notice or obtain consent where required by applicable law. A policy revision does not by itself authorize a use of previously collected information that requires additional notice or authorization.
