These terms govern your use of BYgo (bygo.app), a light planning tool for photographers operated by Taushik Mandal, Barcelona, Spain.
By using BYgo, you agree to these terms. If you do not agree, do not use the site.
What BYgo is
BYgo provides light condition data, shooting briefs, and photography planning information based on publicly available weather and astronomical data. It is a planning aid. It is not a guarantee of conditions.
Weather is unpredictable. The sun does not always do what the data suggests. BYgo gives you the best available information. What happens when you get there is between you and the sky.
What you can do
You can use BYgo freely for personal and professional photography planning. You can share links to BYgo results. You can reference BYgo in your own content with attribution.
What you cannot do
You cannot scrape, copy, or reproduce BYgo’s content, data, or shooting briefs for commercial purposes without written permission. You cannot use BYgo to build a competing product without permission. You cannot attempt to reverse-engineer, interfere with, or damage the site or its underlying systems.
Accounts and email
If you create an account or subscribe to the BYgo digest, you are responsible for keeping your login details secure. You can unsubscribe at any time using the link in any email we send you.
Intellectual property
The BYgo name, design, shooting briefs, and written content are the property of Taushik Mandal. Weather and astronomical data is sourced from third-party providers and remains their property.
Limitation of liability
BYgo is provided as-is. We do not guarantee that the site will always be available, accurate, or error-free. We are not liable for any loss or damage arising from your use of BYgo or your reliance on information it provides.
Photography involves risk. Going out at dawn in an unfamiliar city is your decision. BYgo is a tool, not a guide, and it does not accept responsibility for what happens in the field.
Changes to these terms
We may update these terms from time to time. The date at the top of this page reflects the most recent version. Continued use of BYgo after changes are posted means you accept the updated terms.
