Tachi

Terms of Use

Effective November 13, 2026

These Terms of Use (“Terms”) form a binding agreement between you and Emin Berkay Dağlar, an individual sole developer (“Operator”, “we”, “us”), and govern your use of the Tachi iOS application and the Tachi web app at tachiapp.com (together, “Tachi”, “the App”) and its paid features. By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. License

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices that you own or control, for your personal, non-commercial use. This license is also subject to Apple's Licensed Application End User License Agreement (the “Apple EULA”), which is incorporated by reference. In the event of a conflict, these Terms control to the extent allowed by the Apple EULA.

The web app is provided free of charge under the same license for your personal, non-commercial use in a web browser. The Apple EULA and the subscription terms in section 5 apply only to the iOS application.

2. Eligibility

You must be at least 13 years old (or the minimum age required in your country) to use the App. By using the App, you confirm that you meet this requirement and that you are legally able to enter into a binding contract.

3. Acceptable use

  • Do not reverse-engineer, decompile, or otherwise try to derive the source code of the App, except where this restriction is prohibited by law.
  • Do not use the App to violate any law, infringe anyone's rights, or distribute malware or harmful content.
  • Do not attempt to disrupt or compromise the App, our servers, or our service providers.
  • Do not import content into the App that you do not have the right to use.

4. Your content

You may import or paste reading content into Tachi. You retain all rights in that content. Your reading content stays on your device and is not transmitted to us, except as described in our Privacy Policy.

5. Subscriptions and payments

5.1 What you get

Tachi offers an auto-renewing subscription that unlocks paid features (“Tachi Pro”). The exact features included in Tachi Pro, the price, and the renewal period are shown on the in-app paywall before you subscribe.

5.2 Billing through Apple

Subscriptions are sold and billed through Apple under your Apple ID. Payment will be charged to your Apple ID at confirmation of purchase.

5.3 Auto-renewal

Your subscription automatically renews for the same period at the then-current price unless you cancel auto-renewal at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period at the price you agreed to when you subscribed.

5.4 How to manage or cancel

You can manage your subscription and turn off auto-renewal at any time in your Apple ID account settings (Settings → your name → Subscriptions on iOS). Cancellation takes effect at the end of the current paid period; you keep access to paid features until then.

5.5 Free trials and introductory offers

Where offered, any unused portion of a free trial is forfeited when you purchase a subscription. If you do not cancel before the free trial ends, your subscription will start and your Apple ID will be charged.

5.6 Refunds

Refunds for subscriptions are handled by Apple under Apple's refund policy. We cannot issue refunds directly. To request a refund, visit reportaproblem.apple.com.

5.7 Price changes

We may change subscription prices. Any price change will apply to renewals after we notify you, in line with Apple's rules. If you do not accept the new price, you can cancel before the next renewal.

5.8 Restoring purchases

If you reinstall the App or use it on another device signed in to the same Apple ID, you can restore your subscription using the “Restore purchases” option on the paywall.

6. Privacy

Your use of the App is also governed by our Privacy Policy, which describes what information we handle and why.

7. Intellectual property

Tachi and its content (other than reading content you import) — including its name, logo, design, code, and copy — are owned by the Operator or its licensors and are protected by intellectual property laws. These Terms do not grant you any rights other than the limited license described above.

8. Disclaimers

The App is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that the App will be uninterrupted, error-free, or that it will produce any particular reading-speed or comprehension outcome.

9. Limitation of liability

To the maximum extent permitted by law, the Operator will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising out of or relating to your use of the App. Our total liability for all claims relating to the App will not exceed the greater of the amount you paid us in the twelve months before the claim and US $25.

10. Termination

You may stop using the App at any time. We may suspend or terminate your access if you breach these Terms or use the App in a way that risks harm to us or others. Sections that by their nature should survive termination — including ownership, warranty disclaimers, limitation of liability, and dispute resolution — will survive.

11. Apple-specific terms

  • These Terms are between you and the Operator only, not Apple.
  • Apple has no obligation to provide maintenance or support for the App.
  • If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App, if any. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
  • We — not Apple — are responsible for addressing any claims by you or any third party relating to the App, including product liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection or similar legislation.
  • We — not Apple — are responsible for the investigation, defense, settlement, and discharge of any third-party intellectual property infringement claim relating to the App.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

12. Changes to these Terms

We may update these Terms. When we do, we will revise the “Effective” date at the top. If the change is material, we will notify you in the App or by email. Continued use of the App after the change means you accept the updated Terms.

13. Governing law and disputes

These Terms are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-laws rules. Disputes will be resolved by the competent courts of Istanbul, Türkiye, except where mandatory consumer-protection laws of your country of residence give you the right to bring proceedings in another forum.
