What it does

Adds a service from a catalogue of 160 Malaysian telcos, insurers and streamers included — or type in anything that is not on the list.
Puts every price on the same footing Weekly, monthly, quarterly and yearly all convert to one comparable monthly figure, so a RM 600 annual charge stops hiding.
Shows the month as a calendar Which days money leaves, and what is due in the next 30 days.
Reminds you before a charge Seven, three or one day ahead, or on the day. On the web these arrive when you open the app — a limit of what browsers allow, and one of the reasons the Android app is next.
Exports everything, always JSON for a full backup, CSV for a spreadsheet. Free at every tier, and free even if you are over the free limit.

What it never does

No account Nothing to sign up for. Langgan does not ask for your email address and has nowhere to store it.
No bank, card or email connection You type in what you pay. Langgan cannot read your statements, and it is not built to — that is a permanent decision, not a missing feature.
No analytics, crash reporting or advertising No third-party SDKs of any kind. Nobody, including us, can see how you use it.
No fetching from anyone else Fonts, logos and the whole service catalogue are bundled into the app. It makes no request to a third party while you use it — a build check fails if one ever appears.
No cloud Your subscriptions live in your browser's own storage on this device. They go somewhere else only if you export them yourself.

What it costs

Free for up to 10 active subscriptions — the whole app, not a trial with features held back. Cancelled subscriptions do not count towards the limit.

Past that, unlimited subscriptions are a one-time RM 19.90. Not a recurring charge: a subscription tracker that bills you monthly is a contradiction.

There is no way to buy it today. The unlock arrives with the Android app, through Google Play, and there is no web checkout. Until then the free limit is the whole story — and going over it never hides, locks or deletes anything you have already entered.

Where this is up to

Langgan is built by one person, who uses it every day and built it to solve their own problem first. The web app is finished and in daily use.

Android is next, and brings proper scheduled reminders and the one-time unlock. iOS follows when it earns Apple's annual fee. There is no cloud sync today, and nothing in the app depends on one.
