Frequently asked questions

Nottle is a daily reflection app for iOS and Android. It's designed as a lightweight mood check-in tool — not a journaling app, not a habit tracker. Each session takes 2–5 minutes: you do a quick mood check, log your energy and a few activity signals, add an optional short note, and receive a single AI observation about your day. Over time, Nottle helps you see emotional patterns without pressure, streaks, or judgment. It's self-reflection made simple.

Most mood checker apps reduce your inner life to a colored dot. Most journaling apps ask you to write paragraphs. Nottle sits in between: a structured daily mood check-in that captures enough signal to be meaningful — mood, energy, activities, a short note — but takes less than five minutes. The result is a private, growing record of your daily experience that the AI uses to surface quiet patterns over time. Think of it as a self-reflection practice that actually fits into a real day.

Nottle is built for that exact experience — you liked the idea of tracking your mood, but streaks started to feel like pressure, or journaling prompts started to feel like homework. Nottle keeps the speed of a mood tracker, drops the gamification, and lets AI do the noticing instead of asking you to write it all out.

No. Nottle is fully usable without an account. Your mood check-ins, reflections, and AI insights are all stored locally on your device. An account is only needed if you want to upgrade to Premium or restore a purchase on a new device. Your data is yours — private by default, never shared without your action.

A daily mood check-in in Nottle takes 2–5 minutes. You select one of five mood states, optionally set an energy level on a slider, tap a few activity tags (sleep, work, movement, weather, etc.), and add a short note if you want. When you finish, Nottle generates one brief AI observation based on what you shared — a calm, non-directive signal, not advice. No long writing required.

None. There are no streaks, no daily goals, and no penalties for missing days. Nottle is designed to feel like a gentle option, not an obligation. You can do a self-reflection check-in every evening, once a week, or only on days that feel heavy. The app welcomes you back without judgment regardless of when you return.

Yes. You can complete a full mood check-in offline — mood, energy, activities, and your note all save locally without internet. AI insight generation requires a connection and will simply be skipped if you're offline. Your reflection is always saved regardless.

After each daily reflection, Nottle sends your mood, energy, activities, and optional note to an AI service — only to generate your insight. It produces one short, observational sentence. It never gives advice, never diagnoses anything, and never tells you what to do. For Premium users, the AI also has access to recent check-in history, enabling it to notice cross-day patterns. Your content is never stored by the AI service or used to train models.

All your daily self-reflection data — moods, notes, activities, insights — is stored locally on your device by default. Nothing is uploaded to our servers without your explicit action. Cloud sync is not yet available, so your data stays private and inaccessible to us.

Only when you have an internet connection and complete a check-in: your reflection note is sent to our AI service solely to generate your insight. It is not stored, logged, used for advertising, or used to train AI models. It is never shared with analytics tools or third parties. See our Privacy Policy for full details.

No. We do not sell your data, use it for advertising, or share your reflection content with third parties for any commercial purpose. Nottle is a reflection app built on the belief that your inner life is not a product.

Go to Profile → scroll to the bottom → tap "Erase local data." This permanently deletes all your reflections, insights, and settings stored on your device. This action cannot be undone.

Your reflections and mood data are stored locally on your device only — we never see the content of what you write. Some anonymized, non-identifying usage data (such as app opens or feature usage, never reflection content) may be retained in our analytics systems (Amplitude, Firebase Crashlytics) and cannot be individually deleted since it isn't tied to a personal account. If you made a purchase, payment records are retained by Google Play or the App Store per their standard policies.

Premium gives you richer AI insights with cross-day context and pattern recognition — the AI can reference your recent check-in history to surface recurring emotional signals. You also get advanced analytics: mood calendar heatmaps, trend analysis across longer time periods, and deeper language that reflects patterns in your daily self-reflection practice. Free users receive the same-day AI observation for every check-in — Premium adds depth, not access.
