1. Who we are

MainQuest is a personal productivity and reflection app with habit tracking, a diary, a calendar, goals, sleep coaching, and an AI assistant called Alfred. It is available on the web (mainquest.center, mainquest.page) and as an iOS app (together, the "Service").

MainQuest is operated by Shivam Banerjee, a sole proprietor in Switzerland ("MainQuest," "we," "us," "our"). He is the controller responsible for the personal data described in this policy, under the Swiss Federal Act on Data Protection (FADP) and, for people in the European Economic Area, the EU General Data Protection Regulation (GDPR).

Shivam Banerjee, MainQuest
Dinkelbergstrasse 5d
4132 Muttenz
Switzerland
Email: betterme.global@gmail.com

This policy covers the website, the web app, the iOS app, and any other service that links to it.

2. The short version

  • We collect what you put into MainQuest so the app can work, plus the minimum needed to run accounts and billing.
  • We do not sell your data, show ads, or use third-party analytics or tracking tools. We count visits to this website ourselves, anonymously (see section 3).
  • Alfred is MainQuest's own assistant and runs on Claude, a model made by Anthropic. Parts of your data are sent to Anthropic to answer you, and are not used to train their models.
  • Health and fitness data is only used for features inside MainQuest, never for advertising.
  • You can delete your account and all of its data from Settings at any time.

3. Information we collect

Account

Email address and password (stored only as a secure hash by our authentication provider, never in plain text), first and last name, and optionally your birth year. If you sign in with Apple or Google where offered, we receive the name and email address that provider shares.

What you create in the app

Diary entries (title, text, date, category, and mood) and your diary categories; habits and their daily completion history; calendars and events (title, time, description); to-do lists; goals and their progress; answers to weekly check-ins; your daily energy level; and app preferences such as theme and what Alfred calls you.

Alfred's memory (paid plans)

Alfred has its own memory, built and stored by MainQuest in our database (not by Anthropic), so it can learn from past experiences with you. It keeps a record of problems you worked through together, the options you considered, and what helped. It can also keep notes about people, places, and topics that matter to you: the name and type of each one, short summaries and quotes, how important and how emotionally charged they seem, and any corrections you make. Summaries, quotes, and corrections are encrypted in our database. The names of people and topics are not.

Health, sleep, and fitness (optional)

Only if you turn these features on. See Section 5 for details.

Voice dictation (optional)

If you dictate a diary entry or a message to Alfred, on the web or in the iOS app, the audio is sent to our transcription provider to be turned into text and is not kept by MainQuest or stored with your account. We record only how many seconds were transcribed, to apply plan limits.

Calendar import (iOS, optional)

If you choose to import from your iPhone's calendars, MainQuest reads the calendars and events you give it access to, and saves the events you import to your MainQuest calendar. You can revoke access at any time in iOS Settings.

Device and usage

A device identifier, used to keep voice dictation on one device at a time and to help prevent abuse. Every plan, Free included, works on as many devices as you like. A log of when you message Alfred and which AI model answered (not what was said), used for daily limits. Your IP address, which is used briefly to prevent abuse and appears in our hosting provider's standard server logs.

Payments

Your plan, trial dates, whether you subscribe on the web or through Apple, and a reference ID (Stripe customer ID or Apple transaction ID). Card details go directly to Stripe or Apple. We never receive them.

Support

If you contact support, we receive your email address, subject, and message.

Stored on your device

The web and iOS apps keep a local copy of your data on your device so they load quickly and work offline. Deleting the app removes the iOS copy; clearing site data in your browser removes the web copy.

Visits to this website

We count visits to mainquest.page ourselves, without cookies or third-party tools: the page viewed, the website that linked to it (just its name, such as google.com), the country your connection comes from, and whether it is a phone or a computer. We do not store your IP address. To count you once a day, we keep a code made from your connection and browser that changes every day, so it cannot follow you from one day to the next. If your browser sends Do Not Track, nothing is counted.

Permissions on your iPhone

The iOS app asks before it uses any of these, and works without them. You can change each one at any time in iOS Settings, then MainQuest.

  • Notifications: reminders for your diary, habits, bedtime, events, and to-dos, check-ins from Alfred, and a heads-up before a free trial ends. They are scheduled on your iPhone; we don't send push notifications from our servers.
  • Microphone: to dictate diary entries and messages to Alfred. Recording happens only while you dictate, and the audio is sent to be transcribed (see Section 8), then discarded.
  • Speech recognition: live transcription while you speak, done on your iPhone.
  • Calendars: read-only, to bring the events from your iPhone's calendars into your MainQuest calendar when you choose to import them.
  • Apple Health: read-only, as described in Section 5.
  • Alarms: to wake you at the time your sleep plan sets, even when your iPhone is on silent.

What we do not collect

Location, contacts, photos, camera, or advertising identifiers. MainQuest contains no advertising, analytics, or tracking SDKs, and does not track you across other companies' apps or websites.

4. Alfred and AI processing

Alfred only works after you agree to this. Before Alfred's first reply, the app explains what is shared and asks for your permission, and you can withdraw it at any time in Settings, after which Alfred stops sending anything to Anthropic.

Alfred is MainQuest's own assistant: its personality, memory, and planning tools are designed and built by MainQuest, and it runs on Claude, a language model made by Anthropic, through Anthropic's API. Each time you message Alfred, we send Anthropic your message and the recent conversation, together with context so Alfred can give a relevant answer: your upcoming calendar, habit progress, recent diary entries, and (on paid plans) the relevant parts of Alfred's memory, decrypted only for that request. On the web, if you ask Alfred to look at a specific period of your diary, it asks for your permission before sending those entries.

Before a request leaves our servers, the names of people, specific places and organisations in what you wrote, your diary and your calendar are replaced with placeholders such as PERSON_1, PLACE_1 and ORG_1, and Alfred's reply is changed back before you see it. Places means addresses, named venues such as a café or hotel, event locations and where you live; organisations means employers, schools and companies named as such. Names of cities and countries are kept, because Alfred needs them to help with travel and plans. The placeholders are made for each request and are not stored. Detection is pattern-based: it catches most of these written in the usual ways, but not all of them, and what you write about someone can be personal even without their name. This applies to every request we send to Anthropic, from the web and the iPhone app alike, including when Alfred's memory is built or corrected. Voice notes are transcribed as audio (see Groq in Section 8) and are not covered by this replacement.

Alfred's memory stays in MainQuest's database. When you message Alfred, it looks up the past experiences and notes relevant to what you wrote and includes only those in the request, so its answer can build on them. Anthropic does not store a memory of you. On the web, if you tell Alfred it remembered something wrong, that note and your correction are sent to Anthropic to rewrite it.

Anthropic processes this data only to produce Alfred's responses. Under Anthropic's commercial API terms, it is not used to train their models, and Anthropic may keep requests for a limited time only for safety and abuse monitoring. Your conversations with Alfred are not stored in our database. They are kept only on your device, and deleted there two hours after the conversation ends. Alfred makes suggestions only. It never makes decisions about you that have legal or similarly significant effects.

5. Health, sleep, and fitness data

All of the following is optional and used only to power features inside MainQuest, such as sleep coaching, daily health scores, and automatically ticking off habits you have completed.

  • Apple Health (iOS): read-only access to sleep, steps, exercise minutes, heart rate and resting heart rate, heart rate variability, blood oxygen, and breathing rate. Sleep is used to work out your actual bedtime, wake time, and sleep efficiency and to adjust your sleep-coaching goal. Steps and exercise minutes tick off matching habits, such as 10,000 steps. The heart and breathing measurements show how well you recovered overnight and which parts of your day run your heart high. MainQuest never writes to Apple Health.
  • Google Health (including Fitbit): the activity, sleep, and health measurements you authorize.
  • WHOOP: profile, recovery, sleep, workouts, daily cycles, and body measurements.
  • Strava: your profile and activities.
  • Garmin: the activity and wellness data you authorize.

For connected services, we store the access tokens that let us fetch this data on your behalf, plus basic profile details such as your display name. From this data we save nightly sleep results, your sleep goal, and daily scores such as a health score and your own ratings.

Health data is never used for advertising or marketing, never sold, and never shared beyond the providers in Section 8. It is not stored in iCloud. You can revoke access at any time: for Apple Health, in iOS Settings, then Privacy & Security, then Health, then MainQuest; for other services, disconnect them in MainQuest's Settings or in that service's own settings.

6. Cookies and similar technologies

MainQuest uses only what it needs to work. The web app stores your sign-in session and a local copy of your data in your browser's storage, and remembers settings such as your theme. These are necessary for the Service, so they don't need your consent. We don't use advertising or analytics cookies, third-party trackers, or pixels in our emails, and we don't do interest-based advertising. Visits to mainquest.page are counted without cookies, as described in Section 3.

You can clear this storage at any time in your browser's settings; you will then be signed out. Some browsers send a "Do Not Track" signal. We don't track you across sites either way, and our visit counter skips browsers that send it.

7. Why we use your data (legal bases)

We process personal data in line with the principles of the Swiss FADP: lawfully, in good faith, only as far as needed, for purposes you can recognise, and accurately. For people in the European Economic Area, the GDPR also requires a legal basis for each use. These are ours:

PurposeData involvedLegal basis
Providing the Service: your account, your content, sync across devices, plan limitsAccount data, what you create in the app, device dataPerformance of our contract with you
Alfred, MainQuest's AI assistantYour messages and the context described in Section 4Your explicit consent, which you can withdraw in Settings

Counting visits to this websiteThe anonymous visit data in Section 3Our legitimate interest in knowing how the site is used
Complying with the law and protecting rightsWhatever the situation requiresLegal obligations; our legitimate interest in defending legal claims

Health data and the content of your diary can be sensitive personal data. We process it only with your explicit consent and only to provide the features you turned on. Withdrawing consent does not affect processing that happened before. MainQuest does not make automated decisions about you that have legal or similarly significant effects.

8. Service providers we share data with

We share data only with the providers below, and only what each needs to do its job. They act on our behalf under contract.

ProviderWhat it does for usWhat it receives
SupabaseDatabase and sign-in (hosted in Frankfurt, Germany)All account and app data
AnthropicPowers AlfredYour messages and the context described in Section 4

AppleiOS subscriptions; Apple Health on your deviceSubscription status
Google, WHOOP, Strava, GarminHealth and fitness connections you choose to turn onAn authorization request from MainQuest; we receive the data listed in Section 5
ResendSends support and account emailsYour email address and message

We do not sell personal information or share it for cross-context behavioral advertising. We may disclose information if the law requires it, or to a successor if MainQuest is sold or merged, in which case this policy continues to apply.

Requests from authorities. We disclose personal data to courts, police, or other authorities only when Swiss law, or a court order recognised in Switzerland, obliges us to. We check each request, disclose no more than it requires, and tell you about it unless the law forbids us to.

9. How long we keep data

  • Your account and content: for as long as your account exists.
  • When you delete your account from Settings, everything linked to it is deleted from our database immediately, and it disappears from backups within 30 days.
  • Voice audio: not kept after transcription.
  • Support emails: kept for up to 12 months after your request is resolved, then deleted.
  • Payment records: kept by Stripe or Apple under their own legal obligations. Records we must keep for accounting are kept for 10 years, as Swiss law requires.

10. Your rights and choices

  • Delete: Settings, then Delete account, on web or iOS. This is permanent. If you subscribe through Apple, also cancel in iOS Settings, because Apple subscriptions can't be cancelled for you.
  • Access and correct: see and edit your content directly in the app.
  • Get a copy (portability): email us and we will send your data in a machine-readable format within one month.
  • Withdraw consent: turn off "Share data with Anthropic" in Settings, disconnect health and fitness services, or revoke Apple Health access, at any time.
  • Object or restrict: email us to object to or limit particular processing.
  • Information: ask what personal data we hold about you, why, and who receives it.
  • Complain: if you are unhappy with how we handle your data, you can contact a data protection authority (see below).

You can exercise these rights by emailing us. We may need to confirm it's really you before we act on a request, and we answer within 30 days. If we can't meet a request in full, we tell you why. These rights apply under the Swiss FADP, the GDPR and the UK GDPR, and we honor the equivalent rights under US state privacy laws, such as California's, wherever you live.

Supervisory authorities. In Switzerland: the Federal Data Protection and Information Commissioner (FDPIC), Feldeggweg 1, 3003 Bern, edoeb.admin.ch. In the European Economic Area, you can complain to the authority where you live or work; the list is at edpb.europa.eu.

11. Security

  • All data is encrypted in transit (HTTPS/TLS) and at rest by our database provider.
  • Every user's data is isolated at the database level, so an account can only read its own records.
  • Alfred's memory summaries, quotes, and corrections are additionally encrypted with a per-user key (AES-256-GCM).
  • Accounts need a verified email address and a password of at least 8 characters.

No system is perfectly secure. If a breach affects your personal data, we will notify you and the relevant authorities as the law requires.

12. Children

MainQuest is not intended for anyone under 16 (or under 13 in the United States), and we do not knowingly collect their data. If you believe a child has given us personal information, contact us and we will delete it.

13. International transfers

MainQuest is run from Switzerland and our database is hosted in the EU (Frankfurt, Germany). Switzerland and the EU recognise each other as providing adequate protection. Some providers, including Anthropic, Groq, Vercel, Stripe, and Resend, process data in the United States. For these transfers we rely on the Swiss-U.S. and EU-U.S. Data Privacy Frameworks where the provider is certified, or otherwise on standard contractual clauses approved by the European Commission and recognised by the FDPIC. You can ask us for a copy of the safeguards that apply.

14. Other sites and services

The Service links to, and lets you connect, services run by others, such as Apple Health, Google, WHOOP, Strava, and Garmin. We don't control them, and their own privacy policies apply to what they do with your data. We encourage you to read them.

15. Changes to this policy

When we update this policy, we change the date at the top. For significant changes, we will tell you in the app or by email at least 14 days before they take effect. Earlier versions are available on request.
