Sparetext is a test service that turns your own phone into an SMS gateway. This page says what we store, why, and how to remove it. We don't sell data, we don't show ads, and we don't use your texts to train any model.

What we store

Your account: name, email, and a scrypt hash of your password (never the password itself).

Your texts: the phone numbers and content of texts you send and receive through Sparetext, their statuses and times, and which phone handled them. They are kept so you, your scripts and your agents can read them, until you delete your account.

Your phones: the name, model, OS and app version each phone reports, its battery and network state, and when it last checked in.

Keys and integrations: hashes of your API keys, the webhook URLs and automations you set up, and a log of the last 50 deliveries to each webhook.

If you turn on Send while locked for an iPhone: the email address you give for it, and when the last wake email went out.

Who else sees anything

Our servers run on Cloudflare (Workers, with the data above stored in Cloudflare D1 in Western Europe). To wake a phone instantly we send the single word “sync” to a random private channel on ntfy.sh; no number or text content is ever sent there. If you turn on Send while locked, Cloudflare Email Sending delivers a short wake email from wake@sparetext.dev to the address you gave; it holds no numbers or text either. Webhooks and automations send your texts only to the URLs you enter. AI apps you connect (such as Claude or ChatGPT) can read and send texts only after you allow them on our consent screen, and you can disconnect them on the API keys page.

The people you text

You are responsible for having the right to text the people you message, and for honouring opt-outs. Texts leave from your own phone and number and are billed by your carrier.

Deleting your data

Settings › Delete account removes your account, phones, keys, webhooks, automations and every stored text straight away. Removing a phone revokes its access immediately.
