What Serenity is

A small notebook for writing down how you feel and who you actually spoke to. You pick a mood from five, add feelings and a note, and the last seven days show up as a small chart. Beside it there is a log of real contact — who, by what means, and how it felt — with a counter for consecutive days that have an entry.

That counter measures what you wrote down. It is not a measure of how connected you are, and the app says so on the page rather than letting the number imply it.

What it is not

It is not a therapist, not an assessment, not a community and not a crisis service. It cannot tell whether you are unwell, and it does not try. There is no score, no diagnosis and no model watching you: the 23 activity ideas come from a fixed list, drawn at random and nudged slightly by what you have logged, and the app states that plainly where the ideas appear.

What is inside

• Daily check-in — a mood, optional feelings, a note, and a seven-day chart.
• Connection log — who you spoke to, how, and how it felt, with a day streak.
• Ideas to try — 23 small things across social, mindfulness, physical, creative and self-care.
• My Board — a private page with writing prompts. No server, no other users, nobody to read it.
• Reminders — an optional daily browser notification at a time you choose.
• Settings — export everything as a file, or delete everything.

Getting help, without a number that does not ring

Serenity deliberately lists no helpline numbers. A helpline number only works inside the country that runs it, and an earlier version showed three US-only numbers to everyone with no hint that they were US-only — useful in the United States, silently useless anywhere else.

Instead it sends you to Find a Helpline, which lists vetted helplines by country with their hours, languages and cost. The app guesses your country from your device's time zone so the link opens the right page, and it always offers to let you pick a different country. Its directory covers 181 countries. It also links to IASP and Befrienders Worldwide. If someone's life is in immediate danger, call your local emergency number.

Where your data goes

Nowhere. Everything is kept in your browser's localStorage on the device you typed it on. There are no accounts, no analytics and no tracking, and the page loads no fonts, scripts or images from any other host — it used to pull a font from Google, which handed Google your IP address every time you opened a mental-health app, and that is gone. Links to outside organisations are ordinary links: following one takes you to a site nobody here controls.

Because the data lives in one browser, clearing site data or switching device loses it. Export from Settings first.
