Frequently Asked Questions

Senzo is a book summary app designed around your real-life challenges — not just categories. You take a short quiz, tell us what you want to improve (like focus, finances, or relationships), and Senzo builds you a personalised reading plan from the world's best nonfiction. Every summary is available in both audio and text and takes around 15 minutes to complete. It's not just a library — it's a daily growth habit.

It starts with a 2-minute onboarding quiz where you tell us your goals and schedule. From there, Senzo recommends the right books in the right order and builds a daily reading plan around your life. Each day you spend 15 minutes reading or listening to a summary. Your progress is tracked with streaks and milestones, and the app adapts its recommendations as you go. The more you use it, the better it understands what you need.

A Senzo summary distils the core ideas, frameworks, and insights from a full nonfiction book into a focused 15-minute read or listen. Our editorial team reads every book and identifies the ideas that are most actionable, most thought-provoking, and most relevant to the challenges our users are working on. Summaries are not auto-generated — each one is crafted by a human writer and narrated by a professional voice actor.

Most summaries take around 15 minutes at a comfortable pace. If you're short on time, you can skim the key takeaways in under 5 minutes using the highlights view. If you want to go deeper, extended summaries and chapter breakdowns are available for select titles. We designed every format to fit into your real life — not the other way around.

Senzo covers a wide range of real-life challenges, including: stopping procrastination, building financial confidence, improving relationships, managing anxiety, developing leadership skills, improving sleep, building self-confidence, sharpening focus, finding purpose, and much more. We add new challenge tracks regularly based on what our community is working on. If you don't see your challenge listed, take the quiz — we may already have the right books for you.

Yes — every summary on Senzo is available in both text and audio formats. Our audio summaries are narrated by professional voice actors, and you can choose from multiple narrator voices depending on your preference. Audio summaries are perfect for commutes, workouts, or any moment when reading isn't practical. You can also switch between text and audio mid-summary and your progress stays in sync.

Yes. Senzo supports offline listening so you can download summaries in advance and access them without an internet connection. This is especially useful for travel, commutes, or areas with limited connectivity. Downloaded content is available through the mobile app and stays synced with your reading progress once you're back online.

Senzo is available as a mobile app on iOS and Android, and is also fully accessible from any desktop or mobile browser. Your account, progress, streaks, and reading plan sync automatically across all your devices. Whether you start a summary on your phone during a commute and finish it on your laptop later — you'll always pick up right where you left off.

Senzo has a library of 2,000+ summaries across all major nonfiction categories, with new titles added regularly. Unlike some apps that prioritise quantity over quality, we focus on books that are genuinely useful for the challenges our users are working on. Every title in our library has been reviewed and approved by our editorial team before publication.

Yes. Each summary page includes a link to purchase the full book if you want to dive deeper. We may receive a referral fee if you buy through our link, but this never influences which books we recommend — our recommendations are driven entirely by your goals and our editorial standards.

Absolutely — we'd love to hear from you. Send us an email at support@senzoapp.com with the subject line "Book Submission" and include the title, a brief description, and why you think it would resonate with our community.

Your full reading history, streak data, completed summaries, and progress stats are all available in the Profile or Progress section of the app. You can see how many minutes you've listened, how many chapters you've completed, and how long your current streak is. We believe tracking progress is one of the most powerful tools for building a lasting habit.

Send an email to support@senzoapp.com with the subject line "Account Deletion Request" and include your registered email address. Please note that account deletion is permanent and cannot be undone — your reading history, streaks, progress, and personal data will all be removed. Make sure you've cancelled any active subscription before requesting deletion to avoid future charges.

Senzo offers flexible subscription plans including a free 7-day trial so you can experience the full app before committing. After the trial, paid plans are available on a monthly or annual basis — annual plans offer significant savings. Visit our pricing page for current plan details and pricing. No credit card is required to start your trial.

If you don't cancel before your trial ends, your account will automatically convert to a paid subscription and you'll be charged for the plan you selected at sign-up. You'll receive a reminder email before your trial expires. To avoid being charged, cancel at least 24 hours before the trial period ends through your Account Settings or by emailing support@senzoapp.com.

You can cancel any time — no questions asked. To cancel: log into your account, go to Account Settings → Subscription, and follow the cancellation steps. Alternatively, email support@senzoapp.com with "Cancel Subscription" in the subject line. Your access to premium content continues until the end of your current billing period. We won't charge you again after cancellation.

Contact our support team via live chat or email at support@senzoapp.com to request a refund. We review refund requests within 5–7 business days and you'll receive a response by email. You may qualify for a refund if you experience verified technical issues preventing normal use. EU residents have additional statutory rights under applicable consumer protection law. See our full Refund Policy for details.

We're sorry about that — it shouldn't happen. Please email support@senzoapp.com immediately with your registered email address and any payment confirmation you have.

Log into your account and navigate to Account Settings → Billing to update your payment details. You can add a new credit or debit card, or switch to a different payment method. Changes take effect on your next billing cycle. If you're having trouble updating your payment info, contact us at support@senzoapp.com and we'll assist you directly.

Go to Account Settings → Subscription and select the annual plan option. The change activates immediately and you'll be charged the prorated difference for the remainder of your current cycle. Annual plans offer substantial savings compared to month-by-month billing — typically equivalent to getting several months free.

All your invoices and payment history are available in the Billing section of your Account Settings. You can view and download individual receipts as PDFs for your records. If you need a specific invoice reissued or need help with your billing history, email support@senzoapp.com and we'll send it over.

No. Your reading history, progress, and in-app activity are used exclusively to personalise your experience within Senzo — to improve recommendations, track your streaks, and tailor your reading plan. We do not sell, share, or licence your reading activity to advertisers or data brokers. Where we use third-party infrastructure providers (e.g. for audio streaming), they operate under strict data-processing agreements that prohibit them from using your data for any other purpose.

The data we collect — such as your quiz responses, reading history, and progress — is used solely to make Senzo better for you. It powers your personalised reading plan, improves book recommendations, and helps us understand which summaries are resonating with users so we can prioritise new titles. You can update your preferences or retake the onboarding quiz at any time from your Profile settings.

When your account is deleted, your personal data — including your reading history, progress, preferences, and profile information — is permanently removed from our primary servers within 30 days. All copies, including backup systems, are fully purged within 60 days of the deletion request. This process is irreversible, so please ensure you no longer need your progress data before requesting deletion.
