Kastling

Terms of Service

Effective date: January 6, 2026 Last updated: January 6, 2026

1. Introduction and scope

These Terms of Service ("Terms") govern your access to and use of apps.kastling.co and all applications offered by Kastling ("Kastling," "we," "us," or "our"), a sole proprietorship based in Karachi, Pakistan.

By visiting apps.kastling.co, joining a waitlist, or purchasing or using any Kastling application, you agree to these Terms in full. If you do not agree, do not use our website or applications.

These Terms cover Kastling Apps: consumer and business software applications developed and distributed by Kastling.

Separate Terms of Service apply to Kastling's sprint-based professional Services for founders, published at kastling.co/terms.

2. Definitions

"Kastling," "we," "us," "our" means Kastling, a sole proprietorship based in Karachi, Pakistan.

"Apps" or "Applications" means software applications developed and distributed by Kastling.

"User" means any individual who downloads, installs, accesses, or uses a Kastling App, or who joins a waitlist for one.

"Payment Processor" means Kastling's authorized third-party payment processor and merchant of record for App purchases and subscriptions.

"You" means the User.

3. Nature of apps

Kastling develops and distributes consumer and business software applications under the Kastling brand. Specific App names, descriptions, and any supplementary product-specific terms are published at the time of release. Where an App has supplementary product-specific terms, those terms are incorporated into these Terms by reference, and prevail over these Terms to the extent of any conflict.

4. Waitlists

Joining a waitlist for a Kastling App is free and does not constitute a purchase. By submitting your email address to a waitlist, you consent to receive a limited number of emails from Kastling about that specific App, including launch notifications and beta-access invitations. You may unsubscribe at any time by emailing hello@kastling.co or following the unsubscribe link in any waitlist email.

5. Payment and billing

App purchases, subscriptions, and in-app transactions are processed by our authorized Payment Processor acting as the merchant of record. When you purchase a Kastling App, your transaction is processed by the Payment Processor on Kastling's behalf. The Payment Processor collects payment, issues receipts, and handles applicable taxes.

By purchasing a Kastling App, you also agree to the Payment Processor's applicable terms of service and buyer terms, which will be presented to you at checkout. In the event of a conflict between the Payment Processor's terms and these Terms as they relate to payment processing, the Payment Processor's terms govern the payment transaction.

Refund terms for App purchases are set out in Kastling's separate Refund Policy at apps.kastling.co/refund.

6. License grant

Subject to payment of applicable fees and your compliance with these Terms, Kastling grants you a personal, non-exclusive, non-transferable, revocable license to download and use the relevant Kastling App for your personal or internal business purposes on devices and platforms specified at the time of purchase.

This license does not permit you to:

(a) copy, modify, translate, or create derivative works of the App or any part of it;

(b) reverse engineer, decompile, disassemble, or attempt to derive source code from the App;

(d) remove, obscure, or alter any proprietary notices, labels, or marks on or in the App;

(e) use the App in any way that violates applicable law or these Terms.

Nothing in this Section limits any non-waivable right granted to you under applicable law, including (for users in the European Union) the right to decompile a computer program for the purposes of interoperability under Article 6 of Directive 2009/24/EC, or analogous rights under the laws of your jurisdiction.

7. Subscription apps

Where a Kastling App is offered on a subscription basis:

(a) Your subscription begins on the date of purchase and auto-renews at the end of each billing period (monthly or annual, as selected) unless cancelled.

(b) You may cancel at any time through your account on our payment platform or by contacting hello@kastling.co. Cancellation takes effect at the end of the current billing period. No partial-period refunds are issued on subscription cancellations.

(c) Kastling reserves the right to adjust subscription pricing on at least thirty (30) days' written notice to you (or such longer notice as required by applicable law in your jurisdiction). Price changes take effect at the first renewal date following the notice period. You may cancel before the price change takes effect if you do not accept the new price; continued use of the App after the change takes effect constitutes acceptance.

8. App availability and updates

Kastling may update, modify, or discontinue any App or feature at any time with or without notice. Where a material change affects paid subscribers, Kastling will provide reasonable advance notice.

Kastling does not guarantee continuous or error-free availability of any App and is not liable for downtime, interruptions, bugs, or compatibility issues beyond its reasonable control.

9. Acceptable use

You agree not to use apps.kastling.co or any Kastling App:

(a) for any unlawful purpose or in a manner that violates applicable law or regulation;

(b) to infringe, misappropriate, or violate the intellectual property rights of any third party;

(d) to attempt to gain unauthorized access to Kastling's systems, infrastructure, or any third-party system;

(e) to engage in any activity that disrupts, interferes with, or imposes an unreasonable burden on Kastling's operations or systems; or

(f) to misrepresent your identity or affiliation in connection with any Kastling app.

10. Kastling's intellectual property

The Kastling name, wordmark, logo, brand identity, website content, design system, and all underlying technology are the proprietary property of Kastling. Nothing in these Terms grants you any license or right to use Kastling's brand assets, trademarks, or proprietary materials except as expressly stated.

11. Disclaimers

To the maximum extent permitted by applicable law, Kastling provides its applications "as is" and "as available" without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

Kastling does not warrant that its apps will meet your specific requirements, be free of errors or interruptions, or produce any particular business outcome.

Nothing in this Section excludes or limits any warranty, condition, guarantee, or remedy that cannot be excluded or limited under the consumer protection laws applicable to you, including (where applicable) the EU Digital Content Directive (2019/770), the EU Consumer Rights Directive (2011/83/EU), and the UK Consumer Rights Act 2015.

12. Limitation of liability

To the maximum extent permitted by applicable law, Kastling's total aggregate liability to you arising out of or in connection with these Terms, whether in contract, tort (including negligence), or otherwise, will not exceed the greater of:

(a) the total fees paid by you to Kastling in the twelve (12) months immediately preceding the event giving rise to the claim; or

(b) USD 100.

Kastling is not liable for any indirect, incidental, special, consequential, or punitive damages, including loss of revenue, loss of profit, loss of data, loss of goodwill, or business interruption, even if advised of the possibility of such damages.

Nothing in these Terms limits or excludes liability for: (i) fraud or fraudulent misrepresentation; (ii) gross negligence or wilful misconduct; or (iii) any liability that cannot be excluded or limited under applicable law.

13. Indemnity

You agree to indemnify, defend, and hold Kastling harmless from any claims, liabilities, losses, damages, and expenses (including reasonable legal fees) arising out of or related to: (a) your breach of these Terms; (b) your misuse of any Kastling app; or (c) your violation of any third-party rights.

This indemnity does not apply where you act as a consumer (within the meaning of applicable consumer protection law) to the extent that such consumer protection law prohibits or limits indemnification by consumers.

14. Third-party services

Kastling Apps may contain links to or integrate with third-party services, tools, or platforms. Kastling is not responsible for the content, privacy practices, terms, or availability of any third-party service. Use of third-party services is at your own risk and subject to those services' own terms.

15. Force majeure

Kastling is not liable for any delay or failure to perform its obligations where such delay or failure results from circumstances beyond Kastling's reasonable control, including natural disasters, acts of government, internet or infrastructure failures, or civil unrest. Kastling will notify you promptly and resume performance as soon as reasonably practicable.

16. Changes to these Terms

Kastling may update these Terms from time to time. Material changes will be communicated by updating the effective date at the top of this page and, where appropriate, by direct notice to registered App users and waitlist subscribers. Continued use of apps.kastling.co or Kastling Apps following notice of a material change constitutes acceptance of the updated Terms.

17. Severability

If any provision of these Terms is found to be invalid, unlawful, or unenforceable under applicable law, that provision will be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible. The remaining provisions continue in full force.

18. Entire agreement

These Terms, together with any product-specific terms published with a particular App, constitute the entire agreement between you and Kastling with respect to their subject matter and supersede all prior discussions, representations, or agreements.

19. Governing law and jurisdiction

These Terms are governed by and construed in accordance with the laws of the Islamic Republic of Pakistan.

Any dispute arising out of or in connection with these Terms shall be subject to the exclusive jurisdiction of the courts of Karachi, Pakistan.

If you are a consumer resident in the European Union or United Kingdom, mandatory consumer protection laws in your jurisdiction apply and are not displaced by this clause. You may also have the right to bring proceedings in the courts of your country of residence.
