FAQ
Questions answered
Is my diary private on Sproker?
Yes. Your diary is completely private by default. No other users, moderators, or Sproker staff can see your entries. You can enable a privacy lock with Face ID, fingerprint, or PIN for an extra layer of security.
How does mood tracking work?
Each time you open your diary, you can select from 15 mood options (joyful, grateful, content, peaceful, energetic, reflective, curious, proud, hopeful, nostalgic, melancholic, lonely, anxious, frustrated, overwhelmed). Over time, these moods build into a color-coded calendar heatmap. Pro and Ultra users also get AI mood detection that suggests a mood based on what you wrote.
What AI features are included?
Free users get a daily writing prompt from a curated bank of 30+ prompts. Pro adds AI-personalized prompts, mood detection from your text, and On This Day memories. Ultra adds conversational AI journaling (a chat-based reflection that becomes a diary entry), monthly insights with pattern detection, monthly narrative reflections, diary-to-story conversion, and life story milestone suggestions.
Can I journal by voice?
Yes, on Pro and Ultra plans. Tap the microphone button and speak naturally. Your speech is transcribed and then polished by AI into clean diary text. You can review and edit before saving.
What are memory capsules?
A memory capsule is a diary entry you seal with a future unlock date. Write a letter to your future self, then set when it should open - your 40th birthday, New Year's Eve, or any date you choose. The entry stays locked until that date.
What is the life story memoir feature?
The life story memoir is a guided autobiography builder. You create milestones for different chapters of your life - childhood, career, love, travel, achievements - and an AI interviewer asks thoughtful follow-up questions to help you go deeper. The result is a structured memoir you can print as a hardcover.
Can I export or print my diary?
Ultra users can export diary entries as a PDF with a date range selector. You can also order a professionally typeset hardcover or paperback of your diary or life story memoir through our print partner.
Do I need to write every day?
Not at all. Write when you feel like it. Streaks are there for encouragement, not pressure. Some people write daily, others once a week, others only when something significant happens. There are no penalties for skipping a day.
Your story is worth telling
Start your diary today. Write one entry, track one mood, remember one moment. The rest follows naturally.
