Terms of Use

Last updated: 11 November 2026

These terms govern your use of the App Store Operator website (https://app-store-operator.com), its dashboard and services (together, the "Service"). The Service is provided by Nefarius Apps Bilgi Teknolojileri Limited Şirketi, Fatih Sultan Mehmet Mah. Balkan Cad. Meydan İstanbul AVM No:62A, 34771 Ümraniye/İstanbul, Türkiye ("Nefarius", "we"). Paid plans are sold and charged by Yusuf Demirci, the founder of Nefarius, in his own name as an individual ("the Seller"), as described in section 3. By using the website, joining the waitlist or creating an account you accept these terms. If you use the Service for a company, you confirm that you may bind it, and "you" means that company.

How we process personal data is explained in our Privacy Policy (https://app-store-operator.com/privacy).

1. The Service

App Store Operator is a growth platform for mobile app developers. It brings together data from the app stores, in-app events and sales: for example editing and publishing App Store metadata, reading and replying to reviews, App Store analytics and sales reports, and in-app event funnels.

2. Early access

The Service is in early access. Sign-ups may be limited or opened in stages; while they are closed, the website lets you join a waitlist.

  • Joining the waitlist does not create a contract for the Service, does not guarantee access and costs nothing. We will email you when sign-ups open.
  • Paid plans are governed by section 3. Nothing in the Service is charged until paid plans open. Before they open, we will tell everyone who has an account by email at least 30 days before charging starts. An existing account is not moved to a paid plan or charged unless its holder chooses a paid plan, and the Free plan's limits apply to it no earlier than 30 days after that email.
  • Features described on the website, including those marked as coming soon, may change, arrive later or not be offered. While the Service is in preview, we may change or remove features with reasonable notice.

3. Plans, fees and payment

  • Who you pay. Paid plans are sold by Yusuf Demirci as an individual (the Seller), not by Nefarius Apps Bilgi Teknolojileri Limited Şirketi. When you subscribe, your contract for the paid plan, covering its price, payment, invoices, refunds and payment disputes, is with the Seller, and the Seller receives your payment. Nefarius provides and operates the Service under these terms, for paying users too. The plans page and the checkout page tell you who the Seller is before you pay.
  • What you see. Stripe Checkout, receipts and invoices show Yusuf Demirci as the seller. The charge appears on your card statement under his name or the App Store Operator name (for example "YUSUF DEMIRCI" or "APPSTOREOPERATOR").
  • Plans. The Service is offered on a free plan ("Free") and on paid plans. The price of each plan and its limits (number of apps, monthly in-app events, history periods, saved funnels, team members) and features are shown on our website and in the Service before you subscribe, and form part of these terms. Features marked "coming soon" are not part of a plan until they are released. An app counts as one app whether it has an App Store listing, a Google Play listing or one of each.
  • Billing periods and renewal. Paid plans are billed in advance, monthly or yearly. A subscription renews automatically for the same period at the price then in force until you cancel it.
  • Prices and taxes. Prices are in US dollars and exclude taxes. VAT and other taxes that apply to you are added according to your billing details, and the total is shown before you pay. Fees charged by your bank or card issuer, such as currency conversion fees, are borne by you.
  • Payment. Payments are processed by Stripe, the Seller's payment provider. Neither the Seller nor Nefarius stores your full card details. By subscribing you authorise the Seller to charge your payment method at the start of each period, including for upgrades and renewals. Invoices and receipts are issued by the Seller; they are available in the billing settings of the Service and may also be sent to you by email.
  • Discounts. A discount or promotional offer, such as the waitlist offer, applies only under the conditions and for the period stated in the offer. After that period the regular price applies.
  • Upgrades and downgrades. An upgrade, and a switch from monthly to yearly billing, takes effect at once, and you pay the prorated difference for the rest of the current period. A downgrade, and a switch from yearly to monthly billing, takes effect at the end of the current paid period; until then you keep your current plan.
  • Cancellation. You can cancel a paid plan at any time in the billing settings of the Service. Cancellation stops renewal: you keep your plan until the end of the period you paid for, and then your account moves to Free.
  • Failed payments. If a payment fails, it is retried for 14 days. Your plan stays active meanwhile and the Service shows a notice. If the payment still fails after that, your account moves to Free.
  • Refunds. Fees are not refunded for partial periods, including after a cancellation or a downgrade. This does not apply where the law requires a refund, or where we end your access or stop offering the Service without a breach on your part (section 13); in those cases the Seller refunds the unused part of a prepaid period. If you are a consumer, your mandatory rights under consumer law are not affected.
  • Refund requests and payment disputes. Write to [email protected] about a charge, an invoice or a refund. The Seller handles these requests and makes refunds to the payment method you paid with. If you dispute a charge with your bank or card issuer (a chargeback), the Seller answers it through Stripe; please contact us first so that we can try to resolve it quickly. This does not limit your rights against your bank or under consumer law.
  • Price changes. Prices may change for future periods. We will tell you by email at least 30 days before a new price applies to you; it applies from your first renewal after that. If you do not accept it, you can cancel before it applies.
  • Usage limits. Exceeding a limit never results in an automatic charge:
    • In-app events: we notify you by email and in the Service at 80% and at 100% of your monthly event limit. We keep accepting events up to 120% of the limit; after that, new events are rejected and not stored until the limit resets at the start of your next billing period (on Free, on the 1st of each month, UTC) or you upgrade. Rejected events cannot be recovered. Store data is not affected.
    • Apps: if your account has more apps than your plan allows, for example after a downgrade, you choose which apps stay active (otherwise the most recently used ones do). The others become read-only: they stay visible with their data, but their store data no longer syncs, their events are not accepted, and they cannot be edited or published to the stores. Nothing is deleted, and an upgrade makes them active again.
    • Saved funnels and team members: saved funnels over the limit are locked but not deleted, and team members over the limit lose access at the end of the period. You choose which ones stay.
  • History after a downgrade. When your account moves to a plan with a shorter history period, including a move to Free after a cancellation or a failed payment, store analytics and event history older than the new plan keeps are deleted 30 days after the change. A later upgrade restores store analytics only as far back as Apple and Google still provide them, so older history may not come back. Records of metadata changes are not deleted on a downgrade; on Free only the last 30 days are shown, and older records become visible again after an upgrade.
  • Who is responsible for what. The Seller is responsible to you for the payment side of a paid plan: charging, invoices, refunds and payment disputes. Nefarius is responsible for providing the Service as these terms describe. Sections 11 and 12 apply to the Seller as they apply to Nefarius. Where mandatory law makes both responsible to you, this split does not limit your rights.

4. Accounts

  • You must be at least 18 and able to enter into contracts, and the information you give us must be accurate.
  • Keep your password secret. You are responsible for what is done through your account unless it was caused by our fault. Tell us at once at [email protected] if you think someone else has access to it.
  • A workspace belongs to the account that created it. Its owner decides who the members are and what they can do, and is responsible for their use of the workspace.

5. App store connections and API keys

To use most of the Service you connect your App Store Connect account (and, when supported, your Google Play account) with credentials you create there, such as an API key.

  • You confirm that you are allowed to give us these credentials and to let the Service act for the related developer account. Create the key with the narrowest role that covers the features you use.
  • We store your credentials encrypted and use them only to perform the actions you request and the syncs you enable. We do not use them for anything else.
  • Changes the Service sends to the app stores (for example metadata or replies to reviews) are made only when you or a member of your workspace ask for them. You are responsible for checking them before you publish and for complying with Apple's and Google's rules and agreements.
  • You can revoke a key at any time in App Store Connect or by removing the connection in the Service.
  • Apple and Google are independent third parties. We do not control their services, APIs, review decisions, data or availability, and we are not responsible for them. If they change or restrict their APIs, the related features may stop working until we adapt them.

6. Your data

  • You keep all rights to the data you enter, connect or send to the Service ("Your Data"). You give us a non-exclusive, worldwide, royalty-free right to use Your Data only to provide, secure and support the Service for you, for as long as you use it.
  • Where Your Data contains personal data of other people (for example reviewers' nicknames, or your app users' events), you are the controller and we process it on your behalf, as described in the Privacy Policy and our data processing agreement. You are responsible for having a legal basis for that data and for informing the people concerned.
  • You can ask us to delete your account, a workspace or the data of a connection you removed by writing to [email protected] from the email address on your account. We delete Your Data within 30 days of your request. Removing a connection in the Service deletes its key at once; the connection's data is kept until you ask us to delete it. If you ask in writing before deletion, we first give you a copy in a common format.

7. In-app events (Events)

If you add Events to your apps, you also accept these rules:

  • You will tell your users, in your app's privacy policy, that you collect usage data through a service provider, and obtain their consent where the law or the app store's rules require it.
  • You will not send names, email addresses, phone numbers, precise location, advertising identifiers, text your users typed, special categories of personal data, payment card data or any other data the integration guide forbids, and you will not use Events in apps for children.
  • Each app's write key is public by design; you are responsible for events sent with it until you rotate or revoke it. We may limit or revoke a key that is abused or endangers the Service, and tell you when we do.
  • Event Data is kept for 13 months and then deleted automatically.
  • Events are collected on your users' devices and may be delayed or lost. Counts and funnels are estimates for product decisions; they must not be used for financial reporting, billing or payments to third parties.
  • You may use and modify the tracker code published in our integration guides in your apps for as long as you use Events; apps you already shipped may keep it afterwards. We keep all other rights in it.

8. Acceptable use

You must not:

  • use the Service in breach of the law, of third parties' rights or of Apple's and Google's agreements and guidelines;
  • connect a developer account or app you are not authorised to manage;
  • try to access other customers' data, test or break the security of the Service without our written permission, or get around its limits;
  • overload the Service, send automated requests outside the documented interfaces, or scrape it;
  • copy, resell, rent or offer the Service to third parties as your own, or reverse engineer it except where the law allows it;
  • upload malware or content that is unlawful, misleading or infringes others' rights.

9. Suspension

We may suspend access to the Service, a workspace or a feature, with notice where practical, if we reasonably believe that it is used in breach of these terms or the law, that it puts the Service or other customers at risk, or that a competent authority requires it. We lift the suspension when the cause is resolved.

10. Intellectual property

The Service, its software, design, texts, logos and the "App Store Operator" and "Nefarius" names belong to Nefarius or its licensors. While these terms apply, we give you a personal, non-exclusive, non-transferable right to use the Service for your own business. No other right is transferred to you.

If you send us suggestions or feedback, we may use them freely without obligation to you.

App Store, App Store Connect and Apple are trademarks of Apple Inc.; Google Play is a trademark of Google LLC. App Store Operator is not affiliated with, endorsed or sponsored by Apple or Google.

11. Availability and disclaimers

We work to keep the Service available, secure and accurate, but during the pre-launch and preview period the Service is offered as it is and as available. In particular:

  • we do not guarantee uninterrupted or error-free operation, or that the Service will meet a specific need of yours;
  • data from Apple, Google and your apps' devices may be delayed, incomplete or revised by its source, and we do not guarantee that it matches the source;
  • suggestions, analyses and figures in the Service are support for your decisions, not professional advice and not a promise of rankings, downloads or revenue.

These disclaimers do not limit any right that the law does not allow to be limited.

12. Liability

  • Nefarius and the Seller are not liable for indirect damage, including loss of profit, revenue or business opportunity, unless it was caused by their intent or gross negligence.
  • For other damage, the total liability of Nefarius and the Seller together, arising from these terms and the Service in any 12-month period, is limited to the greater of the fees you paid for the Service in that period and the Turkish lira equivalent of USD 100.
  • These limits do not apply to damage caused by intent or gross negligence (Turkish Code of Obligations Art. 115), to death or bodily injury, or where the law otherwise forbids limiting liability. If you are a consumer, your mandatory rights under consumer law are not affected.
  • You are liable to us for damage, third-party claims and administrative fines arising from your breach of sections 5 to 8, including reasonable legal costs, to the extent caused by your fault. We will tell you promptly about such a claim and let you take part in the defence.

13. Term and termination

  • These terms apply as long as you use the Service.
  • You can close your account at any time by writing to [email protected].
  • We may end your access to the Service with at least 30 days' notice by email, or immediately if you seriously or repeatedly breach these terms and, where the breach can be remedied, do not remedy it within 7 days of our notice. If we stop offering the Service altogether, we will give at least 60 days' notice.
  • After termination, Your Data is handled as described in section 6. Sections that by their nature continue (in particular 6, 10, 12 and 16) survive termination.

14. Changes to these terms

We may update these terms, for example when the Service or the law changes. We will publish the new version on this page and, if you have an account, tell you by email at least 30 days before a material change takes effect. A change to your detriment applies to you only if you accept it; if you do not, you may close your account before the change takes effect, and the earlier version continues to apply until then. Changes required by law or needed at once for security may apply sooner.

15. Other terms

  • Neither party is responsible for failure to perform caused by events beyond its reasonable control (force majeure), such as natural disasters, war, epidemics, actions of authorities, or outages of networks, hosting providers or the app stores.
  • You may not transfer your rights under these terms without our consent. We may transfer them to a successor of our business and will tell you if we do. The Seller may transfer the paid-plan contract to Nefarius or to such a successor; you will be told by email beforehand, and your plan, price and paid period stay the same.
  • If a provision is invalid, the rest of these terms remain in force, and the invalid provision is replaced by a valid one that comes closest to its purpose.
  • We contact you by email at the address on your account or waitlist entry; you contact us at [email protected]. Electronic records kept in the ordinary course of business may be used as evidence; you may prove the contrary.
  • These terms are published in Turkish and English. If they differ, the Turkish version prevails for users established or resident in Türkiye and the English version for everyone else.

16. Governing law and disputes

These terms, including the paid-plan contract with the Seller, are governed by the laws of the Republic of Türkiye. If you are a merchant or a public legal entity, the courts and enforcement offices of İstanbul (Çağlayan) have jurisdiction. If you are a consumer, the statutory rules apply, including your right to apply to the consumer arbitration committees and consumer courts of your place of residence. Mandatory consumer protection rules of the country where you live continue to apply to you.
