Legal

01Terms of Service

These Terms govern access to and use of ProjectATC (the “Service”). By creating an account, purchasing Pro or using the Service, you agree to them. ProjectATC is operated by Timeo Geimer, established in Belgium (“ProjectATC”, “we”, “us”). Belgian enterprise number (BCE/KBO): 1042.779.395. You can contact us at help@projectatc.com.

What the Service is

ProjectATC is a browser-based solo air-traffic-control training simulator for entertainment and practice. It is not approved training, professional certification or a real-world navigation tool. It is not affiliated with or endorsed by an aviation authority or online flight-simulation network and must never be used for actual flight operations.

Airport and procedure information is based on public aviation data. Surface layouts use OpenStreetMap data and may be simplified. Airline designators and radio callsigns are published identifiers used descriptively. Simulated information may be incomplete, outdated or unsuitable for real operations.

Accounts

You must provide a valid email through Google sign-in or a magic link and are responsible for activity on your account. You must be at least 16, and must have a parent or guardian's permission where the law of your country requires it. Do not share or resell your account. Contact us promptly if you believe it has been compromised.

Plans & billing

A Free tier is available. Pro is a single payment, not a subscription. It unlocks the paid features on the purchasing account for as long as ProjectATC continues to operate the Service; there is no renewal or recurring charge.

Prices are in US dollars (USD) and include applicable taxes. Pro costs $14.99 USD as a one-time payment. Any current discount, code and deadline are shown on the pricing page. There is no subscription. Your bank may apply currency conversion charges if your account uses another currency.

The purchase transaction is with Lemon Squeezy, our Merchant of Record and authorised reseller. Lemon Squeezy collects payment and applicable tax, issues the invoice or receipt and handles payment disputes and refunds. The final total and applicable terms are shown before payment. The transaction is also governed by Lemon Squeezy's Buyer Terms. These ProjectATC Terms continue to govern use of the Service.

Delivery, functionality & compatibility

Pro access is normally activated automatically after Lemon Squeezy confirms payment. It requires the buyer to sign in with the account linked at checkout. ProjectATC requires a current desktop web browser with JavaScript, an internet connection and local storage enabled. Spoken pilot audio also requires browser speech support and an audio output; voice availability and quality differ by browser, operating system and installed voices. No special hardware or downloadable application is required.

Acceptable use

• No attempts to break, overload, maliciously scrape, reverse engineer or circumvent the Service or its paywall.
• No unlawful, infringing, or abusive use.
• No automation that disrupts the Service or unfairly manipulates scores or leaderboards.
• We may suspend or terminate accounts that materially violate these Terms, normally after notice where appropriate.

Intellectual property

The Service, its original code, design and content are owned by us or our licensors. Subject to these Terms, you receive a limited, personal, non-exclusive and non-transferable licence to use the Service. Public aviation data, OpenStreetMap data and third-party identifiers remain subject to their respective rights and licences.

Disclaimers & liability

We aim to keep the Service available and materially consistent with its description, but do not promise uninterrupted or error-free operation. Planned maintenance, provider outages, browser changes and events beyond our reasonable control may affect availability.

Nothing in these Terms excludes the legal guarantee of conformity for digital content or digital services, liability for fraud, wilful misconduct, death or personal injury caused by negligence, or any other right or liability that applicable law does not allow us to exclude. Subject to those mandatory rights, we are not liable for indirect or consequential loss, loss of opportunity, or reliance on the simulator for real aviation activities.

Changes & termination

We may update the Service to improve functionality, security, data accuracy or compatibility. We will give reasonable notice where a change materially and negatively affects paid access, when required by law. We may update these Terms prospectively; the effective date appears at the top of this page.

You may stop using the Service and request account deletion at any time. Belgian law governs these Terms, without depriving consumers of mandatory protections available in their country of residence or restricting any court jurisdiction they cannot legally waive.

02Privacy Policy

Privacy policy updated: 11 October 2026.

Timeo Geimer is the data controller for personal data processed to operate ProjectATC. Questions and rights requests can be sent to help@projectatc.com. We collect only the data needed to provide, secure and improve the Service.

Data we process

• Account: email address, authentication provider, unique user id and sign-in data.
• Purchase entitlement: Free/Pro status, Lemon Squeezy order or subscription identifiers, entitlement source and refund status. ProjectATC does not receive complete card details.
• Training progress: session setup and results, per-position scores, grades, scenario outcomes, tutorial completion, certifications, logbook statistics and notable events. Signed-in Pro progress is synced to the account; some signed-in tutorial progress is also synced.
• Daily Challenge: score, grade, movements, airport, challenge date and a generated public handle. The public leaderboard does not display your email address.
• Optional product analytics, only with your consent: pages and product actions, simulator sessions, airport, duration, grade, purchase-funnel steps, first-touch campaign/referrer and a random device identifier. We do not use this information for third-party advertising.
• Marketing choice: only when you actively opt in, the consent wording and version, source, date, selected topics and any later withdrawal.
• Support and technical data: messages you send us and standard security, request and error logs processed by our hosting providers, which may include IP address and user agent.

Why we process it

• Contract: authenticate you, deliver Free/Pro access, save requested cloud progress, operate the Daily and provide support.
• Legitimate interests: secure the Service, prevent fraud or leaderboard abuse, diagnose operational failures.
• Consent: collect optional usage and performance statistics, or send optional marketing emails if you separately subscribe. You can withdraw either consent at any time.
• Legal obligations: retain or disclose records where tax, accounting, consumer or other applicable law requires it. Lemon Squeezy separately handles transaction records as Merchant of Record.

Providers and recipients

• Supabase — accounts, authentication, cloud progress, product statistics after consent and server functions. Our database is hosted in Ireland. Support, operational services and server-function execution can involve other locations. See data locations and the data processing terms.
• Lemon Squeezy — independent Merchant of Record for payments, tax, invoices, fraud prevention, order support and refunds. Its privacy policy applies to its own processing.
• Vercel — hosting and delivery through a global network, including technical request information. Optional visit and performance statistics require your analytics consent. See its privacy policy and data processing terms.
• Resend — withdrawal receipts and support copies; marketing only after a separate opt-in. It processes recipient addresses, message content and delivery information. Stored data is held in the United States, even when an EU sending region is used. Email and log data on the Free plan is retained for 30 days; contacts and preferences are managed separately. See its data locations and retention and data processing terms.
• Google — the Google sign-in interface can load when you open the sign-in dialog. You may instead use an email magic link. Google processes technical request information and the sign-in information when you choose that method. Fonts are served directly from ProjectATC, without requests to Google Fonts.
• esm.sh — delivers the browser authentication software. The CDN receives technical request information, such as your IP address and the requested resource, when the module loads. This delivery is separate from optional product analytics.
• aviationweather.gov and OpenStreetMap / Overpass services — supply weather and airport layout data, normally through our server proxies. If a layout proxy is unavailable, the browser can contact Overpass mirrors operated at openstreetmap.fr, overpass-api.de, kumi.systems or private.coffee. These requests reveal technical connection information and the requested airport area, but do not include your ProjectATC account id.

An EU database or email sending region does not mean all processing stays within the European Economic Area. Some providers operate globally or store data outside the EEA. Provider documents above describe the relevant safeguards, including standard contractual clauses where applicable. You can contact help@projectatc.com for information or a copy of the safeguards applicable to your data, subject to necessary protection of confidential information.

We do not sell personal data or share it with data brokers or advertising networks.

Browser storage and analytics choices

Necessary browser storage supports authentication, Free progress and logbook data, interface and onboarding preferences, and pending checkout information. It also remembers your privacy choice for up to 180 days, whether you accept or refuse analytics.

Optional analytics are off until you select “Accept analytics”. If you accept, we use Supabase for product statistics and Vercel for visit and performance statistics. Product events may be linked to your signed-in account. A random browser identifier and campaign attribution are kept in your browser for up to 90 days. Your choice applies to this browser on this website; other browsers or devices have their own choices.

You can refuse analytics and still use the game, sign in and purchase Pro. Use the “Privacy choices” button in the website footer to change your choice. The game page has no footer control; return to the website to change it. Refusing stops new optional analytics and removes the browser analytics identifier and campaign attribution. Events already received are not automatically erased by withdrawing consent; you can request deletion using the contact below. Withdrawal does not affect the lawfulness of processing based on consent before its withdrawal.

Payment confirmation, refunds, security records and requested cloud progress remain necessary for providing the service and meeting applicable obligations. Analytics consent is separate from the optional email subscription. We do not use advertising cookies or cross-site advertising pixels.

Email updates

Account creation does not subscribe you to marketing. If you tick the optional email box, we use your consent to send the selected ProjectATC drills, major release notes and occasional Pro offers. Every marketing email includes an unsubscribe link; you can also withdraw consent by contacting us. Withdrawal does not affect processing that occurred before it.

Retention

• Account, access and training progress: kept while your account exists so that you can return to your access and saved progress. Inactivity alone does not close a purchased Pro account. You may request deletion.
• Optional product statistics: scheduled for removal after 90 days by a daily cleanup, normally within the following 24 hours. A limited hold may apply to records needed for an ongoing rights request or a specific dispute, until that matter is resolved.
• Marketing preferences: kept while your account exists and as needed to respect your choice, including a withdrawal. Necessary consent evidence or suppression details may be kept separately to demonstrate compliance and prevent unwanted emails.
• Routine support: kept for 12 months after the matter is closed. If a message is needed for a specific dispute or legal obligation, only the necessary record is retained until the relevant claim or retention period ends.
• Purchase, refund and withdrawal records: kept as necessary to deliver paid access, resolve the request and meet applicable accounting or legal duties. Where Belgian tax retention rules apply, necessary accounting records are kept for 10 years after the relevant tax period, or from the applicable statutory starting date. Unrelated marketing data is not needed for this purpose. Lemon Squeezy separately keeps its transaction records.
• Technical logs and backups: retained according to the hosting provider's applicable service settings and retention cycle. A deletion in the live service may remain in a restricted backup until that backup expires. If a backup is restored, relevant deletions must be reapplied before the restored data is used in the live service.

Data stored only in your browser remains until you clear the website's local data; optional browser identifiers and privacy choices have the expiry periods described above. We cannot clear website data on all your other devices remotely.

Your rights

Depending on the processing and applicable law, you may request access, a copy, correction, deletion, restriction or portability of your personal data, object to processing based on legitimate interests, and withdraw consent. Email help@projectatc.com with the request and the email address linked to your account. You do not need to buy Pro to exercise these rights.

We may request proportionate information to verify your identity. Do not send your password or sign-in tokens. We normally respond without undue delay and within one month of receiving the request. If complexity or the number of requests requires an extension, we will explain the reason within that first month; the extension may be up to two further months where permitted by law. Requests are normally free of charge.

A data copy is provided in a commonly used electronic format. Deleting an account removes its cloud training progress and leaderboard entries. An account deletion request also covers optional statistics that can be linked to you. Records needed for a legal obligation or a specific claim may be retained with restricted access. We will explain any such exception. Requests about Lemon Squeezy's independent transaction processing can also be addressed to Lemon Squeezy.

You may also lodge a complaint with the Belgian Data Protection Authority or the supervisory authority in your country of residence. If we cannot fulfil a request, we will explain why and the available complaint and judicial remedies.

Security & changes

We use access controls, row-level database rules and server-side payment verification to protect account data. No internet service can guarantee absolute security. We may update this policy when the Service or legal requirements change and will post the new effective date here.

03Refund & Withdrawal Policy

Single payment

Pro is not a subscription, so there is no renewal to cancel. You can try Free before buying. Your Lemon Squeezy receipt identifies the purchase seller and provides your order details.

Withdrawal period

If you are an EU/EEA consumer, the general withdrawal period for this distance contract is 14 calendar days from conclusion of the purchase contract, without giving a reason. Send your clear statement before the period expires. Missing legally required withdrawal information can extend this period under applicable law. Other mandatory rights in your country remain available.

ProjectATC provides ongoing access to a hosted digital service. Starting that service is not the same as fully performing it. For services, loss of the right requires full performance and the legally required prior express consent and acknowledgement. Different rules apply to digital content supplied without a physical medium: an exception requires express consent to early supply, acknowledgement of the loss of the right and the required contract confirmation. We do not assume that activating Pro proves any of these conditions.

Any claimed exception must be supported by the applicable contract and checkout evidence. A general acceptance of terms or this policy alone is not a withdrawal waiver.

How to exercise withdrawal

Use Withdraw from Pro, send a clear statement to help@projectatc.com, or contact the purchase seller using your Lemon Squeezy receipt. Include your name, purchase email and order details if available. You do not need to sign in, explain your reason or use our template. If you do not know your order number, give the purchase date and purchase email so we can locate it.

Keep a copy of your statement. The online form records the receipt date/time and provides a reference and an email acknowledgement. Receipt acknowledges your statement; it is not a decision on refund eligibility. A failed form does not prevent withdrawal by email.

Refund timing and method

Where withdrawal applies, payments must be reimbursed without undue delay and no later than 14 calendar days after notification of withdrawal, using the original payment method unless you expressly agree otherwise, without reimbursement fees. Lemon Squeezy processes the payment refund as the purchase seller. Bank processing can affect when the credit appears; it does not change the seller's reimbursement deadline.

If you expressly requested early performance of a service, a proportionate amount for service actually supplied may be payable only where the applicable law and required prior information allow it. No automatic activation fee or deduction applies under this policy.

Outside statutory rights, ProjectATC does not offer a separate commercial change-of-mind guarantee. This does not turn statutory refunds into discretionary requests. Lemon Squeezy may also grant refunds under its own policy.

Faults, non-delivery and legal conformity

The no-voluntary-refund rule does not apply where Pro is not delivered, the digital service is materially non-conforming, a payment is duplicated or unauthorised, or another statutory remedy applies. Please contact us first so we can restore access or correct the problem. Depending on applicable law and the circumstances, available remedies may include bringing the Service into conformity, a proportionate price reduction, termination or a refund.

How refunds affect access

Approved refunds are processed by Lemon Squeezy. A full refund revokes the Pro entitlement linked to the order; a partial refund does not normally revoke access unless otherwise agreed or required. Payment disputes and chargebacks may also suspend the related entitlement while they are investigated.

04Contact

Product support, complaints, privacy requests and withdrawal or refund questions: help@projectatc.com. Please include the email linked to your account and, for payment questions, the Lemon Squeezy order number. Do not send card details.

We will try to resolve complaints directly. Consumers may also contact Belgium's independent Consumer Mediation Service after first attempting to resolve the matter with us. Use of mediation does not remove the right to bring a claim before a competent court.
