Privacy
Last updated 18 August 2026
Replyku drafts replies to messages — email, WhatsApp, DMs, anything. This page explains exactly what happens to what you type, who else sees it, and what is kept.
The message you paste
When you ask for a draft, the message text, your note about what you want to say, and your format, tone and length choices are sent to our server, and from there to the model provider that generates the reply.
We do not write any of it to a database or a log file. It exists in memory for the length of the request and is gone when the response finishes. There is no account, no history, and no way for us to retrieve a past draft.
The model provider is DeepInfra. Your text passes through their systems to be processed, and their handling of it is governed by their own privacy policy, not ours.
Kept in your browser
If you use the writing-samples field to teach Replyku your voice, those samples are saved in your browser's local storage so you do not have to paste them again. They stay on your device and are only sent to the server when you ask for a draft. Clearing the field, or clearing your browser data, removes them.
Your light or dark theme preference is stored the same way.
A cookie remembers which language you last used, so a visit to the site root sends you to the right one. It holds nothing but 'en' or 'id' and lasts a year.
Your IP address
The server keeps a short-lived count of requests per IP address to stop one visitor from flooding the service. This lives in memory, is not written down, and is discarded within a couple of hours of your last request.
Advertising
This site shows ads from Google AdSense. Google and its partners use cookies and similar technologies to serve and measure ads, and may use your prior visits to this and other sites to personalise what you see.
Google's ad script runs on the page alongside the rest of the site. Be aware that this means a third party's code is present in the same page where you paste message text. If that matters to you, an ad blocker or a private window will stop it loading.
If you are in the European Economic Area, the UK, or Switzerland, you are asked for consent before any personalised advertising is set up, and you can change or withdraw that choice at any time through the same prompt.
You can review and adjust what Google collects at google.com/technology/ads and in your Google account's ad settings.
Who else is involved
DeepInfra — runs the language model that writes the drafts, and therefore processes the text you submit.
Google AdSense — serves the advertising described above.
Nothing else. There is no analytics, no tracking pixel, and no third party beyond these two.
Children
This site is not directed at children under 13, and we do not knowingly collect information from them.
Changes and contact
If this policy changes, the date at the top of the page changes with it.
