Terms of Use
Effective May 21, 2026
By downloading, installing, or using WriteFlow ("the App"), you agree to be bound by these Terms of Use ("Terms"). If you do not agree, do not use the App.
These Terms cover both distribution channels:
- iOS / iPadOS, distributed via Apple's App Store
- macOS, distributed as a direct download from this website
Where a clause applies only on one platform, it is marked iOS only or macOS only.
1. Description of service
WriteFlow is an AI-powered writing tool that provides:
- Text rewriting and style adjustment
- Translation into 50+ languages
- AI text generation (emails, replies, posts)
- Customizable AI tiles and presets
On iOS / iPadOS the Service is delivered through a keyboard extension plus host app. On macOS it is delivered through a standalone application that integrates with the system via Accessibility.
The Service requires an active internet connection for AI features to function.
2. Developer identity
WriteFlow is developed and published by Juraj Gajdos, an independent developer based in the European Union.
3. Eligibility
To use WriteFlow, you must be at least:
- 16 years of age in the European Economic Area
- 13 years of age in the United States
- The minimum age required by applicable law in your jurisdiction
4. License
I grant you a limited, non-exclusive, non-transferable, revocable license to use WriteFlow on your personal Apple devices in accordance with these Terms.
4.1 iOS / iPadOS — Apple's standard EULA
For App Store distributions, your use of WriteFlow is also governed by Apple's Licensed Application End User License Agreement (EULA). Where these Terms and Apple's EULA conflict, Apple's EULA prevails for the App Store distribution.
4.2 macOS — Direct-download EULA
For the macOS direct-download build, no Apple EULA wraps your use of the App. Instead, the following terms apply directly:
- You may install and run WriteFlow on Mac computers that you own or control
- You may not redistribute the App, the DMG, or the embedded artifacts
- You may not modify, decompile, reverse-engineer, or attempt to derive the source code (except as expressly permitted by mandatory applicable law)
- The App auto-updates via the Sparkle update framework. Updates are signed with my EdDSA key and verified before installation. You may decline an update; Sparkle will not install an update without your explicit consent.
- Your license terminates automatically if you breach these Terms. Upon termination, you must uninstall the App.
5. Acceptable use
You agree not to use WriteFlow to:
- Generate content that is illegal, harmful, threatening, abusive, defamatory, or otherwise objectionable under applicable law
- Generate spam, phishing messages, or fraudulent content
- Impersonate another person or entity
- Attempt to reverse-engineer, decompile, or extract source code, API keys, or service credentials from the App
- Circumvent or disable any security features, the rate limit, or the subscription gate
- Resell, sublicense, or redistribute the App or its outputs as a standalone service
- Use the Service in any way that violates applicable laws or regulations in your jurisdiction
I reserve the right to suspend or terminate access to the Service for users who violate these Terms.
6. AI-generated content and third-party AI service
- AI suggestions are generated by OpenAI. When you use an AI feature, your text is sent to OpenAI for processing via the WriteFlow edge function hosted on Supabase
- By accepting the in-app privacy consent, you agree to this data being sent to OpenAI for processing
- AI suggestions may contain errors, inaccuracies, biases, or inappropriate content
- You are solely responsible for reviewing, editing, and using any AI-generated content
- WriteFlow does not guarantee the accuracy, completeness, or suitability of AI-generated suggestions
- You should not rely on AI-generated content for medical, legal, financial, or other professional advice
- You are responsible for ensuring that your use of AI-generated content complies with the laws of your jurisdiction
7. Intellectual property
- The WriteFlow app, including its design, code, icons, and branding, is owned by me and protected by applicable intellectual property laws
- Content you input into WriteFlow remains yours. I claim no ownership over your text
- AI-generated suggestions provided to you may be used freely by you without restriction
8. Subscriptions and payments
WriteFlow Pro is a recurring subscription with three plans:
- Monthly — €6.99 per month
- Six Months — €39.99 per six months
- Yearly — €59.99 per year
All prices are in EUR and apply globally. Currency conversion (where applicable) is handled by your card issuer or Apple.
8.1 iOS / iPadOS — App Store
On iOS / iPadOS, payment is processed through Apple's App Store. By purchasing, you also agree to Apple's standard terms for auto-renewing subscriptions:
- Your subscription auto-renews at the price shown unless cancelled at least 24 hours before the end of the current period
- Manage or cancel at any time in Settings → [your name] → Subscriptions on your device, or at apple.com
- Refunds are handled by Apple under Apple's Refund Policy
8.2 macOS — Web Billing
On macOS, payment is processed by Stripe Payments Europe, Ltd. acting as merchant of record under Stripe Managed Payments, via RevenueCat Web Billing. Stripe is responsible for VAT / sales-tax collection and remittance.
- Your subscription auto-renews at the price you originally paid unless cancelled before the end of the current period
- Manage or cancel at any time via your billing portal
- Refunds for macOS purchases: I offer a 14-day refund on all new Pro subscriptions for any reason, in line with EU consumer protection. To request a refund, email starsync.dev@outlook.com from the address linked to your purchase
- After 14 days, refunds are at my discretion and limited to exceptional circumstances (e.g. technical inability to use the Service)
9. Right of withdrawal (EU / EEA users)
If you are a consumer in the European Union or European Economic Area, you have the right to withdraw from a digital content purchase within 14 days under EU Directive 2011/83/EU.
9.1 iOS / iPadOS
Withdrawal for App Store purchases is handled by Apple under their refund process. By purchasing through the App Store, you acknowledge and agree that you request immediate performance of the service, and you acknowledge that you lose your right of withdrawal once the digital content has been fully provided.
9.2 macOS
Withdrawal for macOS web purchases is honored directly by me under Section 8.2: I refund any new subscription within 14 days for any reason, on email request to starsync.dev@outlook.com. Beyond 14 days, the right of withdrawal does not apply because the digital service has been provided in full.
You may cancel auto-renewal at any time without giving a reason; this does not affect the current paid period.
10. Free tier
Without an active Pro subscription, WriteFlow allows up to 5 AI requests per device per day. Daily counters reset at midnight in your local time zone. The free-tier limit is enforced server-side and may be adjusted over time without notice.
11. Consumer rights
11.1 EU / EEA users
Nothing in these Terms affects your statutory rights as a consumer under EU law, including rights under the Consumer Rights Directive (2011/83/EU) and the Digital Content Directive (2019/770/EU). Where these Terms conflict with mandatory consumer protection laws, those laws prevail.
11.2 Australian users
Under Australian Consumer Law, goods and services come with guarantees that cannot be excluded. Nothing in these Terms purports to modify or exclude the conditions, warranties, and undertakings implied by the Australian Consumer Law. If applicable consumer law implies a condition, warranty, or term that cannot be excluded, my liability is limited to the extent permitted by law.
11.3 All other users
If you reside in a jurisdiction with mandatory consumer protection laws, nothing in these Terms limits or excludes your statutory rights under those laws.
12. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." I MAKE NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
I do not warrant that:
- The Service will be uninterrupted, timely, secure, or error-free
- AI-generated results will be accurate or suitable for any particular purpose
- The Service will meet your specific requirements
13. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, I SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE.
My total liability for any claim arising from or related to these Terms shall not exceed the amount you paid for the App in the twelve (12) months preceding the claim.
Nothing in these Terms excludes or limits liability for:
- Death or personal injury caused by negligence
- Fraud or fraudulent misrepresentation
- Any other liability that cannot be excluded or limited under applicable law
14. Indemnification
To the extent permitted by applicable law, you agree to indemnify and hold harmless Juraj Gajdos from any claims, damages, or expenses arising from your violation of these Terms, content you generate or distribute using the Service, or your use of the Service in violation of applicable law. This section does not apply to the extent prohibited by the consumer protection laws of your jurisdiction.
15. Account and sign-in
You may use WriteFlow anonymously (subject to the free-tier limit) or sign in to sync your subscription across devices. Sign-in providers:
- iOS / iPadOS: Sign in with Apple, Continue with Google, Continue with email (one-time code)
- macOS: Continue with Google, Continue with email (one-time code)
Sign in with Apple is not offered on macOS because Apple's provisioning policy does not allow that capability on Developer ID direct-download builds. Email and Google together cover the same cross-platform sign-in case.
Signing in stores a Supabase user ID and your email address (Section 1.3 of the Privacy Policy). You can sign out at any time from Settings. Account deletion requires emailing starsync.dev@outlook.com.
16. Termination
I may suspend or terminate your access to WriteFlow at any time for violation of these Terms, with reasonable notice where possible. Upon termination, your license to use the App is revoked. You may terminate your use at any time by uninstalling the App. Uninstalling does not automatically cancel a paid subscription — you must cancel via Apple ID Settings (iOS) or the RevenueCat billing portal (macOS).
17. Changes to these terms
I reserve the right to update these Terms at any time. Changes will be reflected by updating the effective date. For material changes, I will provide notice through the app. Continued use of the App after changes constitutes acceptance of the revised Terms. If you do not agree to the updated Terms, you should stop using the App.
18. Governing law and dispute resolution
These Terms shall be governed by and construed in accordance with the laws of the Federal Republic of Germany, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG).
18.1 EU / EEA consumers
If you are a consumer in the EU / EEA, you may bring proceedings in the courts of your country of residence. You retain the benefit of any mandatory provisions of the law of your country of residence. You may also use the European Commission's Online Dispute Resolution (ODR) platform to resolve disputes online.
18.2 Users outside the EU / EEA
Any disputes arising from or relating to these Terms shall be subject to the jurisdiction of the competent courts of the Federal Republic of Germany. However, if mandatory laws of your country of residence provide you with the right to bring proceedings in your local courts, that right is preserved.
19. Export compliance
The App may be subject to export control laws. You agree not to export or re-export the App in violation of any applicable export control laws or regulations.
20. Severability
If any provision of these Terms is found to be invalid or unenforceable by a court of competent jurisdiction, the remaining provisions shall continue in full force and effect.
21. Entire agreement
These Terms, together with the Privacy Policy and (for iOS / iPadOS distributions) Apple's Licensed Application End User License Agreement, constitute the entire agreement between you and me regarding the use of WriteFlow.
