We’ve gathered all the important info right here. Explore our FAQs and find the answers you need.
How long does it take to integrate Whisp into my app?
Integration with Whisp is designed to be quick and painless. Most teams can expect to be up and running within just a few hours thanks to our clear, well-structured documentation and helpful examples.
Where is my data hosted and is it GDPR compliant?
All data is securely stored on servers located in the European Union. Whisp is fully GDPR compliant, ensuring your users’ privacy and data protection are always prioritized.
Can Whisp integrate with my existing authentication system?
Yes. Each user signs in with your existing authentication (e.g. username and password), after which they receive a JWT and refresh token. The JWT is used for all subsequent requests, while the refresh token ensures seamless renewal when the JWT expires.
How secure is Whisp?
Whisp places security at the core of its infrastructure. All data is stored in encrypted form, and our systems undergo extensive testing to maintain the highest standards of reliability and protection.
What happens if my app grows faster than expected?
Whisp is built to scale with your growth. Performance remains consistent even as your user base expands. If your MAU exceeds your current plan, you can choose whether to pay per-user overage fees or automatically upgrade to the next plan tier.
What if I have an existing solution and want to migrate to Whisp?
Migration is fully supported. User data can be imported, though the exact migration time depends on your current data structure. Get in touch with us to discuss your setup and we’ll guide you through the process.
