Privacy Policy
Last updated: 2 August 2026 · Operated by Alexey Shuliakouski
Linsu is a local-first routine app. Your routines live on your iPhone, and everything except buying Pro works with no connection.
What Linsu does not do
All of this describes version 1.0, the version this policy is dated for:
- No accounts — no sign-ups, email addresses or passwords to use the app
- No analytics, telemetry, crash reporting or usage statistics
- No advertising, ad identifiers or ad networks
- No third-party trackers
- No selling, sharing or transferring your data — to anyone, for any purpose
- Nothing you write is used to train any AI model
- No location, contacts, photos, microphone, camera or health data access
- Local-first — your device holds the real copy of your data
What the current version does
Version 1.0 has no server and no backend, and sends none of your data anywhere. Your routines, steps, timings and history do not leave your iPhone unless you deliberately export them.
The only network traffic Linsu causes is Apple's own: opening the Pro screen asks the App Store for current subscription prices, and subscribing hands the purchase to Apple to process. Nothing you have written is part of either exchange, and we never see your payment details. Everything else in the app works with no connection at all.
Everything you create is stored locally, in Linsu's private app storage:
- routines, steps and durations
- your daily items and their completion history
- settings and comfort preferences
- whether you have purchased Pro
This data is included in your iPhone's own backups (iCloud Backup or encrypted local backup) if you have those enabled. That is Apple's backup of your whole device, controlled by you — we have no access to it.
Notifications
Linsu schedules local notifications so your routine steps arrive on time. These are created and delivered by iOS on your device. Nothing is sent through a server, and no push tokens exist.
Live Activities
If you start a routine, Linsu can show a Live Activity on your Lock Screen and Dynamic Island. This is rendered on-device by iOS from data already on your device.
Purchases
Linsu Pro is sold through the App Store. Purchases are handled entirely by Apple — we never see or receive your payment details. Linsu asks StoreKit a single question: whether this Apple Account owns Linsu Pro. Apple's handling of purchase data is covered by Apple's Privacy Policy.
Apple provides us with anonymised, aggregated sales figures. These cannot identify you.
Exporting your data
Settings includes a backup export that writes your data to a file you choose. Once you export it, that file is yours and is outside Linsu's control — if you put it somewhere shared, the usual care applies. Linsu does not upload it anywhere.
Deleting your data
Delete the app and everything Linsu stored on your device goes with it. If you would like to keep your routines first, export a backup before deleting.
Children
Linsu is a general-purpose tool with no ads, no external links to unmoderated content, and no communication features. It requires no account and asks for no personal details from anyone, including children.
Not a medical app
Linsu is a planning and routine tool. It does not diagnose, treat, or provide advice about any condition, and it stores no health data. Nothing in the app should be taken as medical, psychological or clinical guidance.
Your rights (GDPR, UK GDPR, CCPA and similar)
Rights of access, correction, deletion, portability and objection concern personal data held by us about you. We hold none. Your data is in your possession, on your device, and you can export or delete it yourself at any time without asking us.
We do not sell or share personal information as those terms are defined under the CCPA.
Changes to this policy
This policy describes the version of Linsu named at the top. When the app changes, this page is updated and re-dated.
