Everything you need to know about Sanza, the cycle-aware productivity app that helps you plan, rest, and thrive on your body's natural rhythm.
Sanza is a phase-based productivity app that helps people with menstrual cycles structure tasks, habits, and rituals around their hormonal rhythm. Think of it as your Cycle OS. A way to live and plan by your own clock, aligning your daily schedule with the natural energy shifts across your menstrual, follicular, ovulatory, and luteal phases.
Sanza is app-first. It is available on the App Store for iOS and works on Android as a Progressive Web App you can install straight from your browser. The website at sanza.app is your space to learn about the app, explore cycle-awareness guides, and subscribe to our newsletter.
Sanza is based in Belgium, with roots spanning Africa and Europe. Our team brings together expertise in cycle tracking, AI, wellness, and ancestral research to build something rooted in both science and real lived experience.
Yes! Sanza is built on the belief that your body is not a problem to fix. It is a compass. A tool for reclaiming your time, energy, and structure on your own terms. We reject the one-size-fits-all productivity model in favour of one that honours hormonal health and bodily autonomy.
Sanza was co-founded by a team with personal experience living with menstrual cycles and backgrounds in AI, wellness, and cultural research. It was born out of real frustration with productivity tools that ignore the body, and a deep desire to build something rooted in hormonal reality.
Most period trackers focus on predicting your next period or logging symptoms. Sanza goes further by turning your cycle data into a full productivity system, suggesting the right tasks, habits, and rituals for each phase. It is a planning tool, not just a tracker.
Yes! Sanza is informed by research on the infradian rhythm, hormonal fluctuations across the menstrual cycle, and their documented effects on cognition, energy, mood, and physical performance. We layer that with AI pattern detection to personalise your recommendations over time.
Sanza is for anyone with a menstrual cycle. We built it to be inclusive and body-affirming. Whether you identify as a woman, non-binary, or anything else, if your body cycles, Sanza is built for you.
Yes! Hormonal birth control can alter or suppress natural cycle phases, but many people still experience cyclical patterns in energy and mood. Sanza adapts to your logged data rather than assuming a textbook 28-day cycle, so it can still give you useful structure.
Sanza was designed with cycle variability in mind, including conditions like PCOS and endometriosis. We see you. The app adapts to your unique patterns rather than relying on rigid averages. Sanza is not a medical tool, but it can help you find structure and self-awareness around your cycle.
Yes! Sanza is available globally on the iOS App Store and as a Progressive Web App in any modern browser. If you have an internet connection, you can use Sanza from anywhere in the world.
Cycle OS is our way of describing Sanza as an operating system for your life that runs on your menstrual cycle. Think about it: just like a phone OS organises your apps and processes, Sanza organises your tasks, energy, and routines around your hormonal rhythm.
Yes! Sanza publishes a newsletter packed with cycle-awareness tips, product updates, and wellness insights. Subscribe at sanza.app. We are also building a community space for people who want to explore cycle-aware living together.
Sanza is independently funded by its founding team. We are not backed by venture capital, so no one is pressuring us to monetise your data. Our revenue model is built on optional premium features, not ads, not selling your personal information.
Your menstrual cycle influences your energy, focus, mood, and creativity all month long. Sanza tracks where you are in your cycle and suggests the best phases for different types of work: deep focus during the follicular phase, creative brainstorming around ovulation, social and collaborative tasks when energy is high, and rest or reflection during menstruation.
Sanza tracks your current cycle phase (Menstrual, Follicular, Ovulatory, Luteal), suggests phase-appropriate tasks and rituals, helps you plan workouts and deep work sessions, highlights your power days, builds habits aligned with each phase, and offers gentle AI support through The Thought Cloud.
The Thought Cloud is a space to capture your ideas, spirals, or intentions without pressure. The app connects those scattered thoughts into actionable tasks, rituals, and reminders, turning mental clutter into a soft, structured plan. This feature is coming soon.
Sanza uses the cycle data you provide, like your period start dates, cycle length, and logged symptoms, combined with AI-driven pattern detection to estimate your current phase. The more you use the app, the more accurate its predictions become.
Yes. You can manually log your period start and end dates, update your average cycle length, and correct any phase estimates. Sanza treats your input as the primary source of truth and adjusts its recommendations accordingly.
During menstruation, Sanza suggests rest, reflection, and low-energy tasks. In the follicular phase, it favours planning, learning, and starting new projects. Ovulation is ideal for social tasks, presentations, and collaboration. The luteal phase is suited to detail work, editing, and wrapping things up.
The luteal phase often brings lower energy, a heightened eye for detail, and a need for more structure. Sanza recognises this and suggests tasks like reviewing work, organising, batch-cooking, and winding down projects, helping you stay productive without pushing past your limits.
Yes! Sanza suggests phase-appropriate movement, from gentle yoga and walks during menstruation to high-intensity training around ovulation. The goal is to align your fitness routine with your hormonal energy so you get better results with less burnout.
Yes! While Sanza provides default rituals and habit suggestions for each phase, you can fully customise them. Add your own habits, adjust suggested rituals, or create phase-specific routines that actually fit your life.
Sanza uses AI to detect patterns in your cycle data, energy levels, and task completion. Over time, it learns your personal rhythm and refines its suggestions, identifying your unique power days, flagging potential dips, and helping you plan ahead with real confidence.
Power days are the days in your cycle when your energy, focus, and motivation are predicted to peak. Sanza identifies these based on your cycle phase and personal patterns, so you can schedule your most demanding tasks when your body is naturally primed for them.
Yes. Sanza can send gentle reminders for phase transitions, upcoming power days, ritual check-ins, and task suggestions. Notifications are designed to be supportive, not intrusive. You can customise or disable them at any time.
Sanza works alongside your existing calendar rather than replacing it. It adds a cycle-aware layer to your planning, showing which types of tasks suit the current phase, when your power days fall, and which rituals to prioritise. Think of it as a hormonal overlay for your schedule.
Absolutely! One of our co-founders has lived with irregular, hard-to-predict cycles her entire life, and Sanza was designed with that reality in mind. The app is built to adapt, not assume. Our AI uses pattern detection to pick up on subtle signals that are often missed, the early whispers, not just the loud ones.
Yes, the core features of Sanza are free. We plan to introduce optional premium upgrades in future versions, but the essential cycle-tracking and phase-based planning tools will always remain accessible to everyone.
You can download Sanza from the Apple App Store for iPhone. On Android or desktop, visit app.sanza.app in your browser and install it as a Progressive Web App. Free and takes less than a minute.
Yes, a lightweight account is needed so your cycle data, habits, and preferences can be saved and synced securely. Sign-up is quick and we only ask for the minimum information needed to get you started.
During onboarding, Sanza asks for your last period start date and your average cycle length. If you know these, the app immediately estimates your current phase. You can refine this data over time as you log more cycles.
That is completely fine. Sanza starts with a general estimate and adjusts as you log more data. Even approximate information helps. The AI will refine its predictions as it learns your personal patterns over the first few cycles.
Yes! You do not need to wait for your next period to begin. Enter your last period start date and Sanza will estimate where you are right now. You can start getting phase-aware suggestions immediately.
Yes. Sanza includes a guided onboarding flow that walks you through setting up your cycle, understanding the four phases, and getting your first set of personalised suggestions. The whole process takes about two minutes.
Many people notice a shift in awareness within their first full cycle, roughly one month. By the second or third cycle, Sanza has enough data to offer increasingly accurate and personalised suggestions. The key benefit is gradual: you start truly understanding your own patterns.
Absolutely! Sanza is designed for beginners and experienced trackers alike. If you are new to cycle awareness, the app guides you through the basics and helps you build understanding one phase at a time. No prior knowledge required.
Nope. Daily logging is optional and entirely up to you. Sanza works with whatever data you provide. Even just period start dates are enough to generate phase-based suggestions. The more you log, the more refined the recommendations become, but there is zero pressure.
Complete the onboarding, enter your cycle information, and explore the phase view to see where you are right now. Check the suggested tasks and rituals for your current phase. You can also browse the habit builder and set up a few phase-aligned habits to start with. You've got this.
Yes. Protecting your cycle data is a core principle at Sanza. We use encryption in transit and at rest, and we never share your personal health information with advertisers, data brokers, or third parties. Your body data belongs to you.
No. Sanza does not sell, rent, or share your personal data with any third party. We are independently funded and our business model is based on optional premium features, not on monetising your health information.
Your data is stored on secure, encrypted servers located in the European Union. We use industry-standard infrastructure with strict access controls to keep your cycle and health information protected.
Yes. Sanza is fully GDPR compliant. As a Belgium-based company, we adhere to European data protection regulations. You have the right to access, correct, export, and delete your personal data at any time.
Yes. You can request full deletion of your account and all associated data at any time through the app settings. Once deleted, your cycle data, preferences, and personal information are permanently removed from our servers.
Yes. All data transmitted between your device and our servers is encrypted using TLS. Data stored on our servers is also encrypted at rest. We treat your cycle and health data with the same level of protection as financial information.
No. Your Sanza account is protected by your personal credentials and is accessible only to you. We do not provide any mechanism for third parties, including employers, insurers, or family members, to access your cycle data.
Deleting the app from your device removes the local data. Your account and server-side data remain intact so you can log back in later. If you want to permanently delete everything, use the account deletion option in settings before uninstalling.
Sanza uses your personal data only to improve your own experience, personalising phase predictions and task suggestions for you. We do not feed individual user data into general-purpose AI training sets. Any aggregated insights used for product improvement are fully anonymised.
We classify all cycle, symptom, and wellness data as sensitive health information and apply the highest level of data protection. Access is strictly limited, processing is minimal and purpose-bound, and we conduct regular security audits to maintain compliance with GDPR and health data best practices.
The four phases are Menstrual (days 1 to 5, when bleeding occurs), Follicular (days 1 to 13, as the body prepares to ovulate), Ovulatory (around day 14, when an egg is released), and Luteal (days 15 to 28, the pre-menstrual phase). Each phase is driven by different hormonal profiles that affect energy, mood, and cognition.
Oestrogen and testosterone rise during the follicular and ovulatory phases, boosting energy, confidence, and verbal fluency. Progesterone rises in the luteal phase, promoting detail-orientation but sometimes reducing social energy. During menstruation, hormone levels are at their lowest, favouring rest and introspection. Sanza maps these shifts directly to task types.
The late follicular phase, roughly days 7 to 13, is often your best window for deep, focused work. Oestrogen is steadily rising, which supports concentration, learning, and memory. Sanza identifies these days and suggests scheduling demanding cognitive tasks during this window.
Yes. Burnout often comes from pushing at the same intensity every day regardless of what your body actually needs. Cycle-aware planning builds in natural recovery periods: resting more during menstruation, surging during ovulation. You work with your energy instead of against it. That sustainable rhythm is how you protect yourself from chronic exhaustion.
In a typical 28-day cycle, menstruation lasts about 3 to 7 days, the follicular phase spans roughly days 1 to 13, ovulation occurs around day 14 and lasts 1 to 2 days, and the luteal phase covers days 15 to 28. Cycle lengths vary widely though, and Sanza adapts to your personal timing.
Cycle syncing is the practice of aligning your diet, exercise, work, and social activities with the phases of your menstrual cycle. The idea is to work with your body's hormonal rhythm rather than against it. Sanza automates this by suggesting phase-appropriate tasks, workouts, and rituals.
During the luteal phase, progesterone rises and oestrogen drops, which can lead to lower verbal fluency, reduced social energy, and increased sensitivity. Many people experience brain fog, irritability, or a need for more structure. Sanza responds by suggesting detail-oriented tasks, quieter routines, and more rest.
Sanza is primarily a productivity and wellness tool, not a fertility tracker or contraceptive method. The phase tracking it provides can complement your understanding of your cycle though. For fertility-specific guidance, we recommend consulting a healthcare provider or dedicated fertility app.
The follicular phase is when oestrogen begins to climb, bringing rising energy, optimism, and mental sharpness. It is ideal for starting new projects, brainstorming, strategic planning, learning new skills, and tackling challenging creative work. Sanza highlights this as a high-potential window.
Ovulation is the hormonal peak of your cycle. Oestrogen and testosterone are at their highest, which typically boosts confidence, communication skills, and physical energy. It is the best phase for networking, presentations, negotiations, and high-intensity workouts. Sanza marks ovulation as your peak social and performance window.
Sanza is available as a native app on the Apple App Store for iPhone. It also works on any modern device, including Android phones, tablets, and desktop computers, as a Progressive Web App through your browser at app.sanza.app.
Sanza is not yet a standalone Android app on the Google Play Store, but it works fully on Android as a Progressive Web App. Open app.sanza.app in Chrome or your preferred browser and use the "Add to Home Screen" option to install it just like a native app.
Yes! The Sanza Progressive Web App works on any device with a modern browser, including laptops, desktops, and tablets. Visit app.sanza.app and you can access the full experience right from your browser.
Yes. Because your data lives in the cloud, you can log in to Sanza on any device and see your cycle data, habits, and preferences. Changes you make on your phone are reflected on your tablet or computer and vice versa.
The Progressive Web App has limited offline support. You can view previously loaded data without a connection. For the best experience, an internet connection is recommended so your data stays synced and you receive up-to-date phase suggestions.
Yes. In line with GDPR, you have the right to export your personal data. You can request a data export through the app settings, which provides your cycle history, logged symptoms, and preferences in a portable format.
Integration with Apple Health and Google Fit is on our product roadmap. We plan to allow syncing of cycle data and activity metrics in a future update. For now, Sanza works as a standalone experience.
Sanza is currently available in English. We are planning to add support for additional languages, including French and Dutch, in future updates as we grow our community across different regions.
The Sanza iOS app is lightweight, typically under 50 MB of storage. The Progressive Web App uses even less since it runs in your browser. Sanza is designed to be efficient and unobtrusive on your device.
Yes! Sanza complements other period trackers rather than replacing them. While apps like Clue or Flo focus on health tracking and predictions, Sanza adds a productivity and planning layer on top. You can use both together for a more complete picture of your cycle.
