Terms of Use
These terms cover the Rostra application and this website. By downloading or using Rostra you agree to them. They are written to be read — if anything is unclear, email us and we will explain it plainly.
1. Who you are dealing with
Rostra is published by Splendid Edge Systems, a sole proprietorship owned by Jalel Kobina Moujaled, based in Ghana ("we", "us"). Rostra is a brand and product of Splendid Edge Systems.
Support: support@userostra.com
We aim to answer support email within two business days.
2. Your licence
Rostra is licensed, not sold. When you buy Rostra Pro you receive a perpetual, non-exclusive, non-transferable licence to use the software for your own personal or business purposes.
- A Pro licence may be activated on up to three computers that you own or control.
- You may not resell, sublicense, rent or redistribute Rostra or your licence key.
- You may not attempt to circumvent licensing, or remove attribution or licence notices.
- The free version may be used indefinitely at no cost, subject to these terms.
3. What you get, and what we may change
The free version includes a limited set of voices and unlimited offline reading. Rostra Pro unlocks the full voice library and additional features described on the Pro page at the time of your purchase.
All updates within your major version (for example, all 1.x releases) are included at no extra cost. A future major version may be an optional paid upgrade. We will not remove features you have already paid for.
4. Refund policy
We offer a 30-day money-back guarantee. If Rostra Pro is not right for you for any reason, email support@userostra.com within 30 days of your purchase and we will refund you in full. You do not need to justify the request.
Refunds are returned via the original payment method through Paddle, our payment provider. Once a purchase is refunded, the associated licence stops being valid and the Pro features return to the free tier.
5. Licence keys and revocation
We may deactivate or revoke a licence key where:
- the purchase was refunded, reversed or charged back;
- the key is being shared, resold or used beyond the permitted number of computers; or
- the purchase was fraudulent.
Outside those cases, a licence you have paid for is yours to keep. We will not revoke a licence to force an upgrade.
6. Payments
Purchases are processed by Paddle acting as merchant of record. Paddle handles billing, invoicing and applicable sales tax or VAT, and their buyer terms apply to the transaction. We never see or store your card details.
7. Third-party components
Rostra includes open-source components, including the Kokoro speech model (Apache License 2.0) and eSpeak NG (GPL-3.0). Those components remain under their own licences, and the required notices ship with the application. Nothing in these terms limits your rights under those licences.
8. Availability and warranty
Rostra is provided "as is". We work hard to make it reliable, but we do not warrant that it will be uninterrupted or error-free, or that the synthesised speech will suit every purpose. You are responsible for making your own backups of any audio you export.
9. Limitation of liability
To the extent permitted by law, our total liability arising from your use of Rostra is limited to the amount you actually paid for it. We are not liable for indirect or consequential loss. Nothing here excludes liability that cannot lawfully be excluded, and if you are a consumer, your statutory rights are unaffected.
10. Acceptable use
You are responsible for the text you convert to speech and for how you use the audio. Do not use Rostra to infringe copyright, to impersonate a real person, or for anything unlawful.
11. Governing law
These terms are governed by the laws of Ghana.
12. Changes
We may update these terms; the date at the top shows when they last changed. Changes are not retroactive — the terms you agreed to when you bought a licence continue to govern that purchase.
