Last updated: October 10, 2026
This translation is provided for convenience. In case of any conflict, the Turkish version prevails.
1.Parties and definitions
These terms govern the use of the CasaX service (the "Service") provided by Ahmet Aksungur (Aksungur Yazılım) (the "Service Provider"). Anyone who signs up for or uses the Service is deemed to have accepted these terms.
- User: a natural person who opens a CasaX account.
- Organization: the workspace of a manager or management company in CasaX; residential complexes, the team and the subscription belong to the organization.
- Complex management: the organization that manages a residential complex or apartment building in CasaX, and the team members it authorizes.
- Resident: a user linked to a unit as an owner, tenant or household member.
2.Description of the service
CasaX is a subscription-based software service for managing residential complexes and apartment buildings, accessed via the web and the iOS and Android apps. It provides dues and charges, collections, expenses, cash and bank accounts, bank transaction matching, online dues payment, requests, announcements, polls, common area reservations, visitor and parcel records, CasaX Assistant and the resident app. The scope of the modules and the plan limits are published on the pricing page.
3.Account and team
- When you open an account, you provide accurate and up-to-date information; you may be asked to verify your email address and phone number.
- You do not share your password with anyone, and you are responsible for the actions taken in your account. If you notice unauthorized use, notify us immediately.
- The organization owner invites team members with a role and a residential complex scope; team members can perform only the actions their roles allow. The organization is responsible for the team's actions.
- Ownership of an organization can be transferred to another user with the current owner's approval.
4.Responsibilities of the complex management
- The complex management is responsible for the accuracy and lawfulness of the apartment, resident, balance due, collection and expense records entered into CasaX.
- Charge, allocation method and late fee settings must comply with the management plan, the resolutions of the owners' meeting and the Condominium Law (KMK). CasaX provides a calculation tool; it does not provide legal or financial advice.
- The complex management is the data controller for residents' personal data; it is responsible for informing residents and, where necessary, obtaining their explicit consent. CasaX is the data processor for this data (see the privacy notice under the Turkish Personal Data Protection Law (KVKK)).
- Obtaining the consents required for SMS messages and emails sent on behalf of the complex, and complying with commercial electronic message legislation, are the responsibility of the complex management.
5.Use by residents
- Resident accounts are free; the complex's CasaX subscription is paid by the complex management.
- To link to an apartment, you use an invitation from the complex management or the complex's invite code; if your phone number does not match the management's record, the link waits for the management's approval.
- Balance due, collection and statement information are records of the complex management. You send any objection to an amount to the complex management; CasaX cannot change these records on your behalf.
- The information that owners, tenants and household members can see differs by role; household members do not see payments or statements.
6.Online dues payments
Dues and other payments to the complex are paid directly into the iyzico or PayTR merchant account that the complex management has opened in its own name and connected to CasaX. CasaX is not a payment institution; it does not act as an intermediary in the payment, does not hold the money and does not take a commission on these payments.
- The payment institution's commission, installments, refunds and chargebacks are governed by the contract between the complex management and the payment institution.
- If the complex management chooses to pass the payment institution's commission on to the resident, this amount is shown on a separate line on the payment screen before payment.
- CasaX records the result received from the payment institution as a collection. If the reported amount differs from the expected amount, the collection is not recorded automatically and is left for the complex management to review.
- Refunds of dues payments are requested from the complex management; the refund is made from the complex management's payment institution account.
- Online payment can be turned off separately for the web, iOS and Android by the platform or by the complex management; in that case, the resident pays by bank transfer to the bank account indicated by the management.
7.Bank integration
If the complex management sets up a BankSocket connection, the transactions of the matched bank accounts are read only, and suggestions for matching them with apartments are generated. Automatic matches are made according to the configured confidence threshold; checking the accuracy of the matches is the responsibility of the complex management. CasaX is not a bank; it does not transfer money between accounts.
8.CasaX Assistant
- The assistant's answers are generated by AI and may contain errors; they do not replace legal, financial or tax advice.
- The assistant looks only at records within the user's permissions; any action to send or save something is performed with the user's approval and is logged.
- The monthly message quota depends on the plan; when the quota is used up, the assistant cannot be used until the next month or until the plan is upgraded.
9.Subscription, trial and payment
- Plans are offered monthly or annually; the annual price equals the price of 10 months. Prices are published excluding VAT.
- New organizations start with a 30-day free trial; no card details are required for the trial. During the trial, the features of the Site 600 plan are available.
- When the trial or subscription ends, the management panel becomes read-only; records are not deleted, and the resident panel and online dues payment continue to work.
- Unless canceled, the subscription renews with the same plan at the end of each period, and the fee for the period is charged to the saved card.
- Cancellation takes effect at the end of the paid period. No refund is given for a used or started period.
- When you change plans, the new plan starts with a new period as soon as the payment is confirmed; no cash refund is given for the unused days of the previous plan.
- Subscriptions started in the iOS and Android apps are subject to the App Store or Google Play terms and are managed there.
- Price changes are notified to the organization owner by email before they take effect and do not affect the paid period.
Details about the purchase are in the pre-contract information form, the distance sales agreement and the cancellation and refund policy.
10.Plan limits and fair use
Each plan has limits on units, residential complexes, team members and monthly assistant messages. When a limit is reached, existing records are not affected; only new items cannot be added. SMS messages are sent from the organization's own SMS provider account, and the fee is paid to the provider. Automated use that places an unusual load on the service's infrastructure may be restricted.
11.Data ownership
The records that the organization and its residential complexes enter into CasaX belong to the organization. The Service Provider processes these records only to provide the Service, keep it secure and fulfill its legal obligations; it does not sell them or use them for advertising. Records can be retrieved with the reports and export tools.
12.Prohibited uses
- Using the Service for unlawful purposes or to process other people's personal data without a legal basis.
- Attempting to access the records of another organization or resident without authorization, or attempting to bypass security measures.
- Reverse engineering, copying or reselling the Service without permission.
- Sending unsolicited bulk messages (spam).
13.Service continuity and support
We take reasonable care to keep the Service running without interruption and announce planned maintenance in advance whenever possible. Interruptions caused by third-party services (payment institutions, the bank connection, SMS providers, app stores) are beyond the Service Provider's control. For support, write to info@casax.com.tr.
14.Suspension and termination
In the event of a serious breach of these terms, failure to meet payment obligations or use that endangers the security of the Service, the Service Provider may suspend the account or the organization, giving prior notice where possible. The organization can cancel its subscription at any time.
15.Limitation of liability
To the extent permitted by law, the Service Provider is not liable for errors in the records entered by the complex management, for decisions made by the management, or for the operation of third-party services. The statutory rights of users who are consumers are reserved.
16.Changes and disputes
- Significant changes to these terms are announced by email or in-app notification before they take effect.
- These terms are governed by Turkish law. The courts and enforcement offices of Istanbul (Çağlayan) have jurisdiction over disputes; the jurisdiction of consumer arbitration committees and consumer courts is reserved for users who are consumers.
- If any provision is held invalid, the other provisions are not affected.
